Cultural differences between China and JapanCulture mainly includes four parts of language and non-verbal behavior, customs, ways of thinking and values, they are a great of impact on chinese and japanese of cross-cultural business negotiation.2 Cultural differences on international business negotiations2.1 Business negotiation countries cultural differencesHelping business people to avoid the different cultures and rude, has formed a $ 100 million market in the United States. “Harris different cultural training”in the market, is very famous. Helping such companies like Intel Corporation and other world-class enterprises for their employees to regularly organize training courses, so that they understand the slightly between different cultures. The following is some of the ways taught by Harris from different cultures and vertices resources. Remembering them, you may not be penny wise and pound foolish in co-operation with foreign Israelis meeting has always been marked by potholes, they do not have the patience to listen to other people gossip in the negotiations. The British are mostly law-abiding, but also makes good business sense. In the negotiations, they do not want to say too much nonsense. Europeans, unlike Americans do like to wear badges, if you insist, then they will feel as a child. Indians like to interrupt each other in the conversation, if you listen to them and not be interrupted or ask questions, they will think you heard inalienable seriously. Negotiations with Malaysian or Japanese, the best time to about 6 seconds of silence. If your negotiations with the Israelis, then do not settle.2.2 Language and non-verbal behavior differences in the impactof language differencesA nation use of the close ties between the language and culture of the nation have. Cross-cultural differences between different cultures negotiations language constraints. The Japanese are speaking face, anything they do not want to say the word "no". They directly refused to make the other embarrassed, even angry, great rudeness. Where negotiations with Japanese businessmen, tone to try to calm and tactful, should not jump to an ultimatum. Also, do not be mistaken for the representation of the Japanesecourtesy is the expression of consent. Japanese tend to talk about them constantly nodded and said: "Hayi!" Like this often tell each other that they pay attention to listen, not "agree".And China belong to the high-context cultures, is passed in the high-context cultures of nonverbal communication and indirect expression and understanding of the important factors of the information, such as posture, eye contact, physical appearance, tone, position, distance, environmental and other non-verbal Factors to communicate. To understand the implications of the discourse, comprehend the implication of the between the lines is necessary. And the chinese seem mild, do not like to argue, with little confrontation speak indirectly obscure, and are often used to silence the non-verbal behavior, a view, or does not agree to certain terms and conditions, and sometimes does not directly say "NO", while silence instead, as an expression of courtesy and respect for each other. Chinese people at the negotiating table is very patient, the so-called "Oriental patience.Chinese people believe in the old saying of "gas wealth, harmony as a prerequisite to achieve value negotiations to avoid friction, Politeness subtle, and the pursuit of permanent friendship and long-term cooperation. Non-language differences. In addition to the use of language to communicate, international business negotiations also widely used non-verbal expression negotiators issued a more subtle way of non-verbal or even more important to accept than language information, and all such signals or signal of total unconsciously.Therefore, when the negotiators issued a different non-verbal signals, with different cultural backgrounds negotiator easily misinterpret these signals, but also awareness of the error not occurred. Personal friction this unconsciously, if not corrected, it will affect the commencement of normal commercial relations. chinese people used silence or endorse a view or not to agree to certain terms and conditions, as an expression of courtesy and respect, this the silent hold a negative view of the Americans naturally difficult to accept their silence regarded as rejected. Under normal circumstances, "laugh" as pleased, the chinese people are sometimes expressed frustration with "laugh", does not endorse.2.3 Value differences international business negotiationsValues differences than language and non-verbal behavior differences ininternational business negotiation hidden too deep, and therefore more difficult to overcome. Values differences in international business negotiations mainly due to the concept of objectivity, equality and punctuality differences caused by misunderstanding and disgust. And the nature of japanese society, the value orientation of the chinese and japanese are also completely different. Due to special historical reasons, China has lost a lot of our own national value orientation, but with the reform and opening up to absorb Western culture after the birth of a the value orientation of the two fusion one hand should be in full contact with Western capitalist society see that the chinese people have a strong desire to learn new things, personality open index than the era of planned economy has been greatly improved. This is very very positive and encouraged, but at the same time must be reminded that due to the previous historical reasons, the character of the chinese people at the same time a mixture of traditional ideas and values of Western society.Summing up, causing instability in the chinese people's value orientation and ease of shaken. abroad hot "after the reform and opening up, the stock hot", in this series of positive behind, the same must admit the blind, assertive harm they bring these ----- blindly pursuit, not judgment, can not be sure of the value orientation of the Chinese people.Japanese nation is a very stoic people, and this led them to flourish in many areas of science and technology, art and also the cause of their nationality Gerry brutal temperament. Become a fascist World War II, when the three countries, one can not get away with this. As for Japanese value orientation, it can be said the relatively "pure." well-known reasons: the post-World War II Japan 100 to be all zeros. perhaps in the long time U.S. jurisdiction, they suffer from cultural aggression. However, this Culture cleaning is also so completely Japanese cultural context of capitalism, since the post-war history, it has been more powerful blood even in cultural mergers of other capitalist countries out of their own road Japan has its unique values: the geographically narrow Japan in order not to be squeezed out of the capitalist bus, only positive, progressive, powerful.At present, China's market economic system has been initially established, the business concept of consciousness tend to have some of the characteristics of the period of the early Western market economy, business negotiations often take the "single win" strategy, economic interests are involved, the more consideration one's own interests, and not too concerned about the interests of the other party. Fairlymature market economy system in the developed countries, Western countries negotiators more "win-win" strategy, and basically be able to consider the actual interests of both sides.2.4 Customs differenceCustoms including some social activities. Chinese people in daily life and work, too proud, and very concerned about their image in the eyes of others, fear of being a joke, arguments and misunderstandings. Americans are more practical, not too concerned about the opinions of others. The American people will not ask each other's age, income, and marriage, they believe infringe on the privacy of others; frequently asked in China. Americans like to frankly express their point of view, the chinese people by a tactful way to express meaning. Americans once asked about something, generally must be given a clear answer. The chinese people advocate "silence is golden". Common in the United States to the elders and juniors meet each other Paijian Bang, Kiss the case, such scenes rarely seen in China. Americans are very punctual, chinese people tend to understand the reason of late. The differences between the many habits still very obvious.3 Business negotiation hidden risks3.1 The existence of the business negotiations between the twoparties to the risk of misunderstandingCommunication between the negotiators of the chinese and japanese Business The most important tool is the language, in addition to non-verbal communication. However, due to differences in both language and non-language cultural communication between the two sides there are obstacles.Between China and Japan, there are many on the verbal and nonverbal cultural differences, misunderstandings and obstacles manufactured for communication between the chinese and japanese negotiations personnel.3.2 Existing so that the risk of business negotiation agenda cannot be unifiedDifferent due to the japanese way of thinking, the chinese negotiators tend to take lateral negotiations, that the negotiations involved lateral spread, that is, to discuss several issues at the same time, progress at the same time, and then forward, until all issues negotiated so far;Lateral negotiations with longitudinal negotiations is two completely different negotiations, if both sides insist on their own way to arrange the negotiating agenda, the negotiations can not be carried out.3.3 The existence of the risk of business negotiations stalled.In order to maintain good interpersonal relationships, chinese negotiators are more willing to take a non-confrontational and non-direct conflict to solve the problem. Even if do not agree with each other's views, and rarely directly reject or refute, but twists and turns to state their views. Japanese negotiators sought to illustrate his point, the language directly, non-distinct, exhibit highly aggressive and argumentative. Straightforward expression of the japanese negotiators will hurt the chinese people's self-esteem, because they do not to their face. Negotiators in China tactful way will make the japanese suited, because he can not truly understand the attitude of the chinese side.These differences will become difficult negotiation process, and even lead to an impasse in negotiation.3.4 The presence of the risk of business negotiations eventuallybroke downFocus on the friendship between the chinese merchants generally can accommodate change the terms of the contract. The japanese focus on interests, once they signed the contract, attaches great importance to the legal nature of the contract. If you sign a contract can not perform, then they would have to pay damages and liquidated damages in strict accordance with the terms of the contract breach, no further room for negotiation. Both different attitudes towards contract after signing a contract compliance difficult, and may make the outcome of the negotiations came to naught. Hospitality of chinese people, will be taken care of on the the visiting japanese sidenegotiators, warm hospitality. This service is great for the japanese side negotiators will feel too extravagance and waste. Japanese equality hospitality, guests would not give preferential. Such hospitality is easily chinese negotiators that the japanese side unfriendly. Different understanding of the two sides will be difficult to trust each other and may be a direct result of the negotiations fruitless.4 In the cultural differences in how the negotiation processNegotiations generally consists of four stages: First pleasantries, talk about some unrelated topic; conduct said; make concessions and the final agreement. Before entering formal business negotiation, people are generally the process of business negotiations, an expectation. This is expected to affect the control of the progress of the talks and negotiation strategy selection often. As negotiators from different cultural differences in terms of language and non-verbal behavior, values and thinking, decision-making, so that they held expectations are not the same, and different expectations would lead these negotiations in the various stages of the negotiations spend time and effort on the differences.4.1 To persuade is to deal with objectionsPersuasion is crucial to negotiations. Understanding of persuasion to convince the way the selection is often due to cultural differences. Will be more time and effort spent on pleasantries and work-related information exchange on cultural focus on the vertical position in relationship, people often tend to convince the stage of the "controversy". Even persuade the way out to save face psychological, often subtle or behind the scenes, but to convince and results with the status of the relationship. As in Japanese culture, it is more presumptuous or tough negotiating strategy may result in loss of face and destroy important personal relationship, so less is used. But sometimes in an informal setting will also be used by the buyer concessions and agreements4.2 AgreementDifferences based on the objective existence of thinking, different cultural negotiations exhibit differences in decision-making, and the formation of the conflictbetween the order of decision-making methods and the overall decision-making methods. When faced with a complex negotiation task, sequential decision of Western culture, especially Britain and the United States are often the big task is decomposed into a series of small tasks. Times to solve the issue of price, delivery, warranty and service contract, every time you solve a problem from start to finish has concessions and commitments, the final agreement is the sum of a series of small agreements. Oriental culture of the overall decision-making methods, however, will have to be at the end of the negotiations, until all issues to make concessions and promises to reach a package agreement.4.3 To establish a cross-cultural awarenessThe so-called cross-cultural exchanges "participants not only rely on their own code, habits, attitudes and behavior, but also experience and understanding of each other's code, habits, attitudes and behavior of all relations, while the latter is considered to be strange new synonym., cross-cultural, including all features and a strange new heterosexual identity and peculiar sense of intimate easygoing and risk, normal things and new things together participants in the center of behavior, ideas, feelings and understanding force is exerted on the relationship between cross-cultural relationship between all the people of the cultural attribution across system boundaries to experience. "in popular parlance refers to people from different cultural backgrounds to participate and cross-cultural carry out the exchange.International business negotiations, the need to strengthen cross-cultural awareness, recognize different cultural type background negotiators in different needs, motivations, beliefs, and learn to know, accept and respect each other's culture. Of course, aware of cultural differences does not necessarily mean that will be able to easily overcome their influence, but at least it will provide an opportunity to overcome, international business negotiations, due to ignorance of the cultural differences and to avoid obstacles. In the correct negotiations awareness under the guidance of foreign negotiators to be flexible and make their own negotiating style and strategy to adapt to different business and cultural impact.4.4 Having come preparedBefore in international business negotiations, we should be familiar with the negotiation of cultural norms, customs, social values and national conditions. The way to do does not cause unpleasant or misunderstandings, as well as affect the progress and results of the negotiations, and we can not only know that fur to a profound understanding. The successful always favors those who are prepared, if you do not make the necessary preparations, it means preparing to fail. A British businessman by long-term market research has found an ideal chinese enterprises, and enterprises in order to establish a good business relationship he decided to visit and visit to this enterprise, I heard the expression send a gift to be able to better sincerity, he would want to buy a gift to his partner.He originally wanted to buy a bottle of liquor, but feared the chinese people believe that he is a jail sentence only, he would like to buy a high-tech product afraid enough humane. Later, he suddenly thought of the the Guangdong local restaurants everywhere worship the Buddha, he thought about the chinese people have such beliefs, so he bought a pack Xiangla gave him chinese partners. The results, of course, he lost the business, a pack Xiangla chinese partners find it difficult to accept.4.5 To overcome communication barriersLanguage is the most important communication tool between countries, but also cross-cultural exchange between the tools. Sometimes, if we can not understand each other's language, it can not be this cross-cultural exchanges. In international negotiations generally communicate in English, if both the mother tongue is not all in English, we have to try to use simple, clear, clear of the English, do not use easy to cause misunderstandings polysemous word puns, slang, idioms, nor to use and easy to causing displeasure words. Cross-cultural exchange can not subjectively believe that the meaning of each other will be in accordance with our wishes, our habits to understand our speech, or from the other side of the speeches we understand what the other would like to express meaning.4.6 To eliminate prejudiceIn cross-cultural communication, people often used to "self-referential" want to be based on the personality and values of their own culture to explain or to determine thebehavior of all other groups, resulting in prejudice to the different cultures, resulting in cultural conflict. In international business negotiations, it is necessary to eliminate prejudice, this will be conducive to negotiations carried out smoothly. Business exchanges with foreign rivals, some of their habits, in our view, is very rigid and even funny. However, we have to respect each other, maintain negotiations situation, so the negotiations harmony. We can not impose their own culture on the people of other countries, other people's culture can not be measured by their country's culture, not to xenophilia, does not adhere to the principles. In international business negotiations, to deal rationally with the obstacles caused due to cultural differences.4.7 Several effective policy responses1. The expert team of portfolio strategies.Japan's negotiating team generally higher, to indicate the great importance to facilitate the division of functions. Small number, not pay enough attention to the lack of sincerity of the negotiations in the japanese view. Negotiating team in Japan generally does not include lawyers, the japanese feel that every step should discuss with the lawyer who is not trusted even with lawyers to participate in the negotiations, is to deliberately create a future legal disputes, unfriendly behavior. The japanese were very patient, indicate their intentions are usually reluctant to take the lead, but be patient, wait and see. Do business, the delaying tactics the japanese used a "weapon". They will force each other gradually lost patience, and know the negotiations each other deadline, they will be more leisurely talk slowly.So the Chinese negotiating team must arrange negotiations, technical, financial, translation and other experts or consultants, especially legal experts. So that in the course of negotiations appear to respond freely to ensure no flaws appear in the contract signed aspects.2. Create an atmosphere strategy.Chinese negotiators to respect the cultural habits of the japanese to create a harmonious atmosphere for negotiations. Japan is a large power distance, very important status symbol here, so the choice of negotiators generally has a certain status and duties in addition to have a certain social skills. Therefore, when negotiating with the japanese in select negotiators to follow the principle of reciprocity, that sent the identity and status of the identity and status of the negotiators should negotiate witheach other to represent a considerable Otherwise, it is considered to be on the other side does not respect . In addition, the lower the status of japanese women in society, so the experience of formal negotiations in general should not allow women to participate in, otherwise they will be skeptical, even showing dissatisfaction.3.Silence and listening strategiesJapanese negotiators to prepare a full and professional characteristics and chinese negotiators in the pre-negotiation to do a good job market information, opponents gathering of information and legal information, the silence strategy can be used in the negotiation process, to think through and listen more, listen get more information on each other in the process.4. Pragmatic language policyChinese negotiators in negotiations with the japanese, our staff of conversation should be tactfully point to calm, polite, show enough patience, impatient and do not have the patience in the japanese view is a sign of weakness . Waiting time, you can engage in investigations elsewhere try to learn more about each other's situation. Note not to publicly criticize the japanese, not bluntly rejected the japanese, and say that you have to further consider. If you had to deny a proposal, but also a clear euphemism rather than the threat of attitude to state the reasons.5 Multi-program strategyFor japanese staff is confidence and focus on the characteristics of the actual interests in the negotiations stalled multi-program strategy can be used to make a conditional concessions. The asking price of the program of multi-program strategy is to determine a variety of pre-negotiation acceptable to both sides in the talks hit impasse to discuss, can provide new ideas to solve the problem for the negotiations.6 Flexible commitment strategyNegotiating team in Japan generally does not include lawyers, the japanese feel that should discuss with the lawyer who is not trusted even with lawyers to participate in the negotiations every step.It is to deliberately create a future legal disputes, unfriendly behavior. Flexible commitment strategy is negotiating with the japanese side can not only attach importance to a person of the other negotiating team, and to persuade everyone. Temporarily unable to fully agree on, not emergency in urging otherwise, can only be counterproductive. Many japanese lawyers are always skeptical, so as long as you can without lawyers to do the main negotiators, they do not bring a lawyer.7 Simple etiquette strategyChinese negotiators can use simple etiquette strategy to the japanese concept of pragmatism negotiations. Useing a simple and practical etiquette is in the process of interaction and the purpose of a friendly and respectful.References[1]刘园:国际商务谈判[M].北京:对外经济贸易大学出版社,2007.1.17[2]周忠兴:商务谈判原理与技巧[M].南京:东南大学出版社,2003.1.1[3]周桂英:中西思维模式差异对中日商务谈判的影响[J].江苏商论,2007[4]杨欣欣:中日价值观念差异及其对语言文化的影响[J].郑州航空工业管理学院学报,1999[5]王耀敏:中日价值观比较探析[J].理论参考,2007(3)[6]杨柳:中日文化价值观在文化风俗上的投影[J].当代教育论坛,2005[7]周新民:中日文化交流[J].北京-中国少年儿童出版社1998.7[8]陈勤建:民俗视野中日文化的融合和冲突[M] 上海-华东师范大学出版社2006.5[9]7wnwc5ey3b:/album/view/bf2d12d5b9f3f90f76c61b28?fr=hittag&al bum=title&tag_type=1 2013.1.22[10]1055273107:/view/8d8c44640b1c59eef8c7b4ac.html2012.10[11]504732809:/view/80be7bed172ded630b1cb685.html2012.7.12[12]/history/special/wushidao/detail_2010_03/21/399937_0.shtml2010.10.23[13]liqihui1990061:/view/0123724769eae009581bec35.html2010.11.3[14]倔倔夫: /view/6548d2f804a1b0717fd5ddae.html 2012.6.2[15]york leon: /p-679139329417.html 2013.1.2[16]linjianghu:/p-776871023244.html2011.11.19AckonwledgementsI’d like to express my sincere thanks to a ll those who have lent me hands in the course of my writing this paper.

deal.II—a General Purpose Object Oriented Finite Element LibraryW.BANGERTHTexas A&M UniversityandR.HARTMANNGerman Aerospace Center(DLR)andG.KANSCHA TUniversit¨at HeidelbergAn overview of the software design and data abstraction decisions chosen for deal.II,a general purposefinite element library written in C++,is given.The library uses advanced object-oriented and data encapsulation tech-niques to breakfinite element implementations into smaller blocks that can be arranged tofit users requirements. Through this approach,deal.II supports a large number of different applications covering a wide range of scien-tific areas,programming methodologies,and application-specific algorithms,without imposing a rigid framework into which they have tofit.A judicious use of programming techniques allows to avoid the computational costs frequently associated with abstract object-oriented class libraries.The paper presents a detailed description of the abstractions chosen for defining geometric information of meshes and the handling of degrees of freedom associated withfinite element spaces,as well as of linear algebra, input/output capabilities and of interfaces to other software,such as visualization tools.Finally,some results obtained with applications built atop deal.II are shown to demonstrate the powerful capabilities of this toolbox.Categories and Subject Descriptors:G.4[Mathematical Software]:Finite element software—mesh handling; linear algebra;G.1.8[Numerical

development of libraries providingfinite element infrastructure to application pro-grams has a long tradition reaching back several decades(see,for example,[Rheinboldt Author’s

of such libraries that can be found by a search of the world wide web.However,the design of only very few of these libraries turns out to be sufficiently general to support more than the one or two applications it was written for initially,and even fewer of the available libraries are structured and documented well enough to allow their application beyond the group of its developers.Consequently,the design of successful and widely applicablefinite element libraries appears to be a hard problem.In this paper,we will examine some of the abstrac-tions and design decisions used in deal.II,an Open Sourcefinite element library that has found significant use with scientists not affiliated with its developers,and that has enjoyed continuous growth since its inception in1997.It can thus be considered one of the libraries that seem to have survived the test of time.deal.II is an object-oriented class library providing all tools needed for simulations with thefinite element ing the structuring means of C++,the different objects used in such a simulation program are well separated,allowing for a wide variation of appli-cations without sacrificing program structure or increasing susceptibility to programming errors.In particular,the strict separation of meshes,finite element spaces and linear algebra classes allows for a very modular approach in programming applications built on deal.II, and to combine the provided functionality in many different ways,suiting the particular needs of an application.The development of deal.II(and its predecessor DEAL)was initiated by the need for a software tool for research in novel adaptive and high-performancefinite element schemes of a number of areas.Most available software tools would either be tuned to performance, but be specialized to one class of applications,while others offerflexibility and generality at a significant waste of memory and computing power.In addition,very few packages were publicly available at the time.Therefore,DEALfilled a gap when its design began in 1992and was the software basis of the development of goal oriented error estimation and adaptive methods for partial differential equations[Becker and Rannacher1998;Kanschat 1996;Suttmeier1996].However,by1997,it became clear that some concepts of DEAL had become too cumbersome,and that important improvements could be made by build-ing on the then recent developments in the C++programming language[Stroustrup1997] and compilers for it,in particular mature support for templates and the standard template library[Stepanov and Lee1995;Plauger et al.2000].Therefore,a fresh start was made with the new implementation of deal.II.deal.II has been used in a large number of projects since then,first in mathematical research on error estimation[Bangerth and Rannacher2003]and discontinuous Galerkin methods[Hartmann2002;Kanschat2006,and references found there],then in other areas of academic research,applied sciences,and industrial projects,some of which are men-tioned in Section7.It is available for download from / under an Open Source license since early2000and has gathered some popularity since then.This web site also features an extensive online documentation,encompassing a com-prehensive reference manual as well as a tutorial for beginners.The library is decisively not designed to solve certain applications.Rather,it is intended to serve as a toolbox containing whatever is needed to write afinite element application program.The main tasks of afinite element program(even for complex nonlinear prob-lems)usually are:(1)Setting up a mesh and thefinite element space,ACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.deal.II—a General Purpose Object Oriented Finite Element Library·3Fig.1.An overview of the collaboration between the most important classes in deal.II.Abstract base classes and groups of classes are shown in italics.The discussion in this article roughly follows thisfigure from left to right.(2)Assembling a discrete linear or linearized system of equations,(3)Solving this linear system,and(4)Postprocessing by numerical evaluation of the solution or visualization.All of these tasks are supported by deal.II,either directly or(for instance in the case of visualization)by interfaces to third party software.To achieve this goal,the library strives to provide a large number of classes and tools that are typically needed for and found infinite element software.While they are designed to cooperate,they do not enforce a particular model or framework for their use,but rather allow programmers to use them in ways appropriate for the structure of a code as dictated by its application area,solution scheme,and software design strategy.Given the size of the library of about300,000lines of code this article is not intended to be a comprehensive description of the library,but rather a description of the software de-sign considerations underlying deal.II,the data abstractions influencing our choice of sep-arating functionality into object-oriented classes,and how they interact.We will demon-strate the use of a few of the objects within the library in small code fragments that show the way of programming with deal.II.The remainder of this article is structured roughly following the collaboration diagram shown in Fig.1:Section2is devoted to the central building blocks of everyfinite element code,in particular meshes(represented by the Triangulation class),shape function spaces(class FiniteElement),and degrees of freedom(class DoFHandler).Sec-tion3discusses how these basic classes are used to build the linear systems arising from the discretization of partial differential equations(classes Quadrature,Mapping,and FEValues).The structures used for efficient linear algebra are described in Section4. Section5lists the connections deal.II offers to other software packages,in particular pre-and postprocessing options available with deal.II.We give an overview over the available documentation in Section6.Section7contains a brief description of some of the many applications built on the library.We conclude with Section8.2.MESHES,FINITE ELEMENT CLASSES,AND DEGREES OF FREEDOM Since deal.II was designed to offer as muchflexibility as possible with reasonable effort, the support offinite elements is split over several classes that can be combined in different ways.In particular,the requirement of using nearly arbitraryfinite element types of vari-able order made it necessary to separate mesh objects from element related data.In this section,we discuss which parts of the library organize the geometric and topological struc-ture of thefinite element space as well as the auxiliary classes combining these propertiesACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.4·Wolfgang Bangerth et al.Triangulation<dim>triangulation;GridGenerator::hyper_cube(triangulation);triangulation.refine(2);Listing1.Creating a mesh of arbitrary dimension.again.2.1Mesh classes and iteratorsThe central class in allfinite element codes describes the mesh.For historical reasons,in deal.II this class is called Triangulation,although the cells it provides are line seg-ments(1D),quadrilaterals(2D),and hexahedra(3D).The triangulation class,as almost the entire library,is organized such that the space dimension is chosen by a template pa-rameter[Bangerth2000].Consequently,it is possible to write codes independent of the space dimension,enabling users to develop and test a program in2D,and later run it in3D without changes.An example of the creation of a Triangulation object is shown in Listing1.Here,the dimension is deliberately left as a template parameter of the enclosing function.A hyper cube[0,1]dim(i.e.,the unit line,unit square,or unit cube,depending on the value of the template parameter dim)is generated and refined uniformly twice into 4dim mesh cells.Note that the dimension is a compile-time constant.Thus,the compiler can optimize on it,and there will be no run-time checks on the dimension impeding per-formance(unlike in many other libraries such as DiffPack[Langtangen2003],libmesh [Kirk et al.2006],or OOFEM[Patz´a k and Bittnar2001],where the space dimension is a run-time parameter).One of the original goals in the development of deal.II was support for adaptive meshing, including both mesh refinement and coarsening.For this purpose,triangulation objects do not only store the respectivefinest cells,but also their(now inactive)ancestors.Conse-quently,a triangulation can be thought of as a collection of trees,where the cells of the coarsest mesh form the roots and children branch off their parent cells.The present ver-sion of deal.II supports regular(bisection)refinement of cells,leading to2,4,or8children per cell in1D,2D,and3D,respectively.The cells of a triangulation therefore form binary trees,quad-trees,or oct-trees,respectively[Rheinboldt and Mesztenyi1980],where the terminal nodes correspond to the active cells,that is,the cells without children forming the mesh in the usual meaning.The non-terminal nodes correspond to inactive cells,i.e.to cells that have children and belong to the mesh hierarchy,but not to the mesh itself.A simple example of an adaptively refined2D mesh along with its tree of cells and a more complex3D mesh is shown in Figure2.The individual levels of these cell trees also form a natural hierarchy for multilevel methods with their obvious importance to the solution of partial differential equations;this feature is exploited in other parts of the library.In order to create such a triangulation we start with a coarse mesh,that can either be generated by deal.II itself in simple cases,or can be read from afile in several meshfile formats(see Section5).The cells of this mesh are then refined recursively,either globally or individually.In typicalfinite element simulations,local refinement is controlled by error estimators,yielding a powerful tool for efficient simulations(see[Bangerth and Rannacher 2003]).Since unstructured meshes do not have a natural,sequential numbering,mesh cells in ACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.deal.II—a General Purpose Object Oriented Finite Element Library·5Fig.2.A simple two-dimensional mesh with cells numbered based on their refinement level

loop over all active mesh cells to compute a“mean”mesh size(follow-up to Listing1).deal.II are accessed by iterators instead of indices.To this end,the Triangulation class provides STL-like iterators that“point”to objects describing cells,faces,edges,and other objects of a mesh.Separate iterator types indicate operations on all objects,only the active subset,and objects satisfying other additional ing these concepts,a loop over all active cells of a triangulation can be written as in Listing2.As afinal remark,we note that triangulations in deal.II only store geometric(the location of vertices)and topological information(how vertices are connected to edges and cells,and neighborship relations between cells).On the other hand,Triangulation objects do not know aboutfinite elements,nodal data,linear systems,etc.It is therefore possible to use the same triangulation object for a number of purposes at the same time.2.2Finite element descriptionsIn the mathematical literature,finite element spaces are usually described by a tuple(ˆP,ˆN) of a shape function spaceˆP and a set of node functionalsˆN on the reference cellˆK[Ciarlet 1978;Brezzi and Fortin1991;Brenner and Scott2002].In deal.II,the reference cell is always the hypercube[0,1]d.The node functionals form a basis for the dual spaceˆP∗. Together with a mapping F K from the reference cellˆK to the actual mesh cell K and rules for the mapping ofˆP andˆN to P and N on K,these completely describe a parametric definition of afinite element space.Alternatively,in a non-parametric description,the spaces P and N may be defined on the mesh cell K directly in special cases.The class structure of deal.II closely follows the definition of parametric elements.We will discuss the definition of polynomial spaces and nodal functionals in the following two subsections.Due to their close relationship,both these concepts are implemented byACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.6·Wolfgang Bangerth et al.classes derived from the FiniteElement class.We defer the discussion of mappings to Section3.2.2.2.1Finite element spaces.At present,the following types offinite element spaces are supported by providing shape functions that span the space:—Tensor product elementsˆP=Q k=span{ˆxα:0≤αi≤k,0≤i≤d}of arbitrary polynomial degree k.In R d,these are polynomials of the formˆϕj(ˆx1,...,ˆx d)=p j1(ˆx1)p j2(ˆx2)···p jd(ˆx d),where the one-dimensional polynomials p i are of maximal degree k.Both hierarchical polynomials or Lagrange interpolation polynomials for arbitrary sets of support points may be used for the one-dimensional basis.The representation above already suggests an efficient implementation in arbitrary dimensions and up to arbitrary order,without having to actually write down the form of d-dimensional shape functions.By choosing the node functionalsˆN appropriately(see the discussion of Fig.3below), these elements exist both in a globally continuous form(“continuous Galerkin”or“CG elements”)as well as a variant that is entirely discontinuous across cell faces(“discon-tinuous”or“DG elements”).—ElementsˆP=P k=span{ˆxα:0≤|α|≤k}of polynomial degree k.P k may be rep-resented by a monomial basis or by a Legendre basis which allows for diagonal mass matrices on parallelograms.Since this space cannot be guaranteed to be globally con-tinuous on quadrilateral/hexahedral meshes,these elements exist only in an entirely dis-continuous variant.—The vector-valued Raviart/Thomas elementˆP=RT k of arbitrary degree k,suitable for the mixed discretization of the Laplacian and someflow problems.This element, while not continuous at faces between mesh cells,has continuous normal components. Consequently,its divergence exists everywhere and the element is conforming with the space H(Ω,div).—The H(Ω,curl)-conforming,vector-valued element by Nedelec with continuous tangen-tial components,widely used in the discretization of Maxwell’s equations[Castillo et al. 2005].—Elements where individual vector components are composed from simpler elements.For example,in the discretization of the mixed Laplacian,a common choice is the combina-tionˆP=RT k×DG Q k of Raviart-Thomas and discontinuous tensor-product elements. deal.II provides a class that is able to construct this d+1-dimensional element from its two building blocks.Similarly,the spaceˆP=[Q k]d of d-dimensional H1-conforming shape functions appropriate for second order equations and systems is composed of d copies of a scalar Q k element.The part of thefinite element interface pertaining to shape functions spanning thefi-nite dimensional spaces on the reference cell is shown in Listing3.Thefirst two functions provide the values and gradients of shape function i at a point p on the reference cell(repre-sented by a dim-dimensional point object).Similar functions exist for higher derivatives as well as for vector valuedfinite elements.Note that the gradient is a vector offixed dimen-sion dim,and is represented as a dim-dimensional tensor of rank1(the matrix of second derivatives would correspondingly be represented by the data type Tensor<2,dim>). ACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.deal.II—a General Purpose Object Oriented Finite Element Library·7 template<int dim>class FiniteElement{public:virtual double shape_value(const unsigned int i,const Point<dim>&p)const=0;virtual Tensor<1,dim>shape_grad(const unsigned int i,const Point<dim>&p)const=0;//...virtual void fill_fe_values(InternalData&,...)const=0;};Listing3.The most important parts of the interface of thefinite element base class as pertaining to the description of shape functions on the reference cell.Derived classes implementing concretefinite element spaces have to override the ab-stract interface laid out above.It is clear that the use of virtual functions of suchfine granularity is very expensive.Consequently,the library strives to use the more powerful function fill fe values provided byfinite element classes that provides data for the FEValues objects discussed in Section3.3below and computes shape function values, derivatives,etc.at a number of quadrature points at once.This sort of data is transferred between the various involved classes in an object of type InternalData.It is the task of the implementation of a newfinite element to design fill fe values as efficiently as possible.Typical optimizations applied here are the use of Horner’s scheme to compute values and derivatives of polynomials at once.Further improvements rely on the special structure of the element.The function values of tensor product elements for instance can be computed very efficiently all at once,if the values of the one-dimensional polynomials are evaluated for each space direction and then these values are multiplied. 2.2.2Node functionals.Node functionals are used in two ways in the description of finite elements.Thefirst is in order to define a basis of thefinite dimensional space:Basis functionsˆϕi are chosen such thatˆN j(ˆϕi)=δij for allˆN j∈ˆN;note that this relation holds for the basis of the shape function space on each cell as well as for thefinite element space as a whole,where the indices i and j range up to the number of degrees of freedom on the reference cell and in the complete mesh,respectively.This use is most frequently implicit:almost allfinite element packages describefinite element spaces as the span of a given number of shape functions,rather than in some more abstract way.deal.II is no exception to this rule.The second use is more practical:By defining node functionals,we can associate degrees of freedom withfinite element solutions.To this end,afinite element needs to describe the number of degrees of freedom per vertex,edge,face,and interior for each cell.For ex-ample,in2D,a continuous bicubic element would have one degree of freedom per vertex, two per line,and four per cell interior.Figure3,shows the locations of degrees of freedom for a few simple elements.This kind of information is consumed by the DoFHandler class described in the next section.Of particular importance are degrees of freedom on the boundary of the cell,since they establish the continuity offinite element functions on the whole mesh by being shared between cells.Vice versa,the global continuity of such a function is already determinedACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.8·Wolfgang Bangerth et al.Fig.3.Degrees of freedom of the standard(left)and discontinuous Q3elements(middle),as well as lowest order Nedelec elements(right).Filled circles indicate node functionals requiring continuity across a face,open circles have no such requirements.Arrows denote continuity only of the indicated vector component.template<int dim>class FiniteElement{public://...as aboveconst unsigned int dofs_per_vertex;const unsigned int dofs_per_line;const unsigned int dofs_per_quad;const unsigned int dofs_per_hex;const unsigned int dofs_per_cell;const FullMatrix<double>&interface_constraints()const;};Listing4.The parts of the interface of thefinite element base class concerning node func-tionals and continuity between cells.by the distribution of degrees of freedom on the surface of the mesh cells.We call this the topology of the element.Figure3shows that several degrees of freedom may be lo-cated on a single geometrical item(in this case edges).Furthermore,thefigure also shows that degrees of freedom,even if they denote interpolation points physically located on the boundary of a cell,may still logically be interior degrees of freedom if they don’t imply continuity conditions,like in the case of discontinuous elements in the middle;for the shown discontinuous element,all16degrees of freedom are logically interior to the cell. Listing4shows the part of thefinite element base class interface that corresponds to node functionals.The constant data members are set by the constructor of the class based on information passed down by derived classes,and describe the logical location of degrees of freedom.The main use of this information is in allocating global indices for the degrees of freedom,as explained in the next section.The frequently-used value dofs per cell is computed from the previous elements; for example,in2D,dofs per cell=4*dofs per vertex+4*dofs per line +dofs per quad.Finally,the function interface constraints returns interpo-lation constraints for hanging node constraints between cells if one cell is more refined than one of its neighbors and is used in the ConstraintMatrix class(see Section3.4 below).ACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.deal.II—a General Purpose Object Oriented Finite Element Library·9Fig.4.Depictions of global enumerations of degrees of freedom on the mesh shown in Fig.2for Q1elements with degrees of freedom associated with vertices(left)and lowest order Nedelec elements with degrees of freedom on cell faces(right).2.3Degrees of freedom handlerA global description of afinite element space is obtained by combining the geometric information on the location and connection of cells provided by a Triangulation with the local description and topology of degrees of freedom on a single cell introduced in Section2.2.2,to provide a global enumeration of the degrees of freedom(DoFs)of afinite element space.Fig.4shows such enumerations for the simple mesh presented in Fig.2 for two differentfinite elements.(Due to hanging nodes,the corresponding spaces are not conforming here;the algorithms used in deal.II to treat this are described in Section3.4.) Mostfinite element packages store the global numbers of degrees of freedom within the triangulation itself,sometimes even together with nodal data and/or matrix entries.How-ever,such a data storage scheme severely restricts the use of these objects.For example, it does not allow to associate differentfinite element spaces with the same triangulation within a program,and it requires that the number of data vectors that need to be stored be hard-coded into the triangulation.To avoid these limitations,deal.II separates this information(in a way somewhat sim-ilar to DiffPack[Langtangen2003]).To this end,the class DoFHandler provides a global enumeration of degrees of freedom,given a Triangulation object describing the mesh and a FiniteElement object describing the association of degrees of freedom with vertices,faces,and cells as described above.A typical code fragment for initializing a DoFHandler based on the triangulation of Listing1is shown in Listing5.With this global enumeration of DoFs,it is up to application programs to allocate as many vectors and matrices as necessary to solve a particular problem,and to associate the entries of matrices and vectors with the indices of degrees of freedom.It is also easily possible to as-sociate an arbitrary number of DoFHandler objects with the same triangulation,possibly representing a number of differentfinite elements on the same mesh.(Note though,that a similar effect can be achieved using the deal.II class FESystem that provides a simple interface for combining simpler elements to form more complex,vector-valued elements suitable for systems of equations.)By default,the DoFHandler class“distributes”degrees of freedom by walking over all cells in the order in which the triangulation presents them,and enumerates all DoFs not pre-viously encountered.This often leads to a more or less random ordering that is sometimes undesirable,for example if ordering-dependent preconditioners(such as SSOR)or solvers (such as marching solvers for advection dominated problems,or sparse direct solvers)areACM Transactions on Mathematical Software,V ol.V,No.N,Month20YY.。
