It can be considered as the top-level interface linking all our software tools.Workbench handles the passing of data between ANSYS Geometry / Mesh / Solver / Postprocessing tools.This greatly helps project management. You do not need worry about the individual files on disk (geometry, mesh etc). Graphically, you can see at-a-glance how a project has been built. Because Workbench can manage theindividual applications AND pass databetween them, it is easy to automaticallyperform design studies (parametricanalyses) for design optimisation.D. DemonstrationDemonstration : 01_WB_Presentation.mp4 •What you can learn in this demonstration :–How to use Workbench project page–How to save, open, archive a project–How to create different analysis–Understand each stage of an analysis–Edit units, properties and files options–Working with parametersE: SummaryANSYS Workbench is a convenient way of managing your simulation projects.Workbench is used to launch the individual software components, and used to transfer data between them.It is easy to see at-a-glace how a model has been built, and determine which files were used for a particular simulation (pairing geometry files to solver runs)Workbench also makes it straightforward to perform parametric analyses (without the user needing to manually launch each application in turn), and makes it easy to simulate multi-physics scenarios like fluid-structure interaction.F. Mechanical OverviewAnalysis types available in Workbench - Mechanical:†•Structural (static and transient):–Linear and nonlinear structural analyses.•Dynamics:–modal, harmonic, response spectrum, random vibration, flexible and rigid dynamics.•Heat Transfer (steady state and transient):–Solve for temperature field and heat flux. Temperature-dependent conductivity, convection, radiation and materials allowed.•Magnetostatic:–Perform various magnetic field analyses.•Electrical:–Simulate electrical devices such as motors, solenoids, etc..† Note, the active ANSYS license dictates what functionality is available to the user. Not all features listed are covered in this Introductory course.… Mechanical OverviewAdd-on licenses for Mechanical:•Rigid Dynamics•Fatigue Module•ACP16.0 Workbench products are available for Windows and Linux operating systems. •Check the ANSYS web site or online documentation for the latest compatibilities.Network licensing capabilities are used for all ANSYS and ANSYS Workbench products.G. APPENDIX. . . Workbench OverviewThe options visible in the left-hand column show all the products (systems) you have licenses for.TIP: If this list appears empty, you have a problem with your licensing. “Analysis Systems” are ready-made stencils that include all the individual systems (applications) needed for common analyses (for example Geometry + Mesh + Solver + Post-Processor) “Component Systems” are the individual building-blocks for each stage of the analysis“Design Exploration” provides tools for optimising designs and understanding the parametric response.. . . Basic WorkflowDragging an Analysis System ontothe project desktop lays out aworkflow, comprising all the stepsneeded for a typical analysis.Workflow is from top to bottom.As each stage is complete, the iconat the right-hand side changes. . . Alternative WorkflowHowever, an analysis could equally well be prepared by selecting theindividual Component Systems that are needed for this analysis, and thenlinking them together with connectors.TIP: There are two ways to create the connectors between the systems:1)Use the mouse to draw a line (eg A2 to B3, B4 to C4 etc)2)Or, simply drop the new system on the cell of the upstream one, and thelink will be generated automatically.. . . Cell StatesAs each stage in the model-build is completed, the state of thecell changes.Status after creating Geometry in A3, not yet opened Mechanical in A4 Status after model has solvedwaiting for post-processing Icon MeaningUp to DateRefresh required. Upstream data has changedUpdate required. Local data has changedUnfulfilled. Upstream data does not existAttention RequiredSolvingUpdate FailedUpdate InterruptedChanges pending (was up-to-date, but upstream data has changed). . . Sharing Data between Different Solvers Workbench can be used to transfer data between solvers. In this 1-way FSI (fluid-structure-interaction) example, we transfer the loads from a Fluent CFD simulation over to a Mechanical system to perform a stress analysisThe square connector shows that the geometry created in cell A2 (CFD model) is being shared with cell B3 (FEA model). The round connector shows that the CFD results are being transferred as a Setup (input) condition to be used for FEA stress analysis.. . . File Location on DiskShould you need to identify the individual files on your disk for each stage of the project, these can be found by enabling View > Files. The resulting table will cross-reference the directory and filename with the project cells.Filename Directory. . . Use of Archive / RestoreThe workbench project comprises many files and directories. If you need to either archivethe project, or bundle it to send to us for a Technical Support query, use the ‘Archive’ tool.This generates a single zipfile of the entire project.When archiving, you can choose whetherto include the computed result files or not(omitting these may make it small enoughto send by email)If you restore an archive you can choosewhere you save (and solve) the project.If you double click on a .wbpz file it willunpack the file to the location given byTools>Options>Folder for TemporaryFilesMost Workbench applications will let you specify key quantities as a parameter (rather than a constant). This will be covered later.In this example:•When creating the geometry inDesignModeler, hole diameter is set tobe an input parameter.•When reviewing the results, themaximum stress is set as an outputparameterWe could just have easily set up a CFD analysis, looking at different loading conditions and reporting the pressure drops.•Clicking on ‘Parameter Set’ lets us vary these parameters. •Four different geometric designs are being tested.•The whole process is automated. Workbench will recursively: i.Create the geometry, based on the parameters in the table ii.Take this into Mechanical and remesh and solve and then the postprocessor•The user just needs to sit back and wait, and the matrix of experiments (each requiring several different applicationsto be launched in turn) is computed automatically.1] Create new row in table with each design (in this case hole diameter)3] The desired result (set up in Mechanical) is reported here2] Click here tocompute all the designs4] The ‘Exported’ option allows snapshots of each DP to be saved to a different project… Starting Mechanical There are two methods of launching Workbench: •From the Windows start menu:•From the CAD systemThe Units menu in Workbench:•Select from predefined unit systems.•Create custom unit systems.•Controls unit display for Engineering Data, Parameters and Charts.•Activate the Units System dialog to unit display preferences.Units can be displayed inthe active Project system oras they were defined in theirsource (e.g. CAD system).Create custom unit systems by duplicating existing systems then modifying. Custom unit systems can be exported and imported.. . . License PreferencesWorkbench license control is handled through the user interface shown below, activated from the Workbench project page:“Tools > License Preferences . . . “. . . License PreferencesThe order of license preference is specified using the up/down arrows (first available is used). •The “Use License” column indicates desired licenses to use (0 = off, 1 = on).Workbench users can specify whether a single license isshared when multiple applications are open, or if eachapplication accesses their own license.31 © 2015 ANSYS, Inc.

ANSYS常见错误和警告及其解决方法1、some contact elements overlap with the other contact element which can cause over constraint。

一些接触单元与其他接触单元重叠，这可能导致过度约束。

解决方法：这是由于在同一实体上，即有绑定接触（MPC）的定义，又有刚性区或远端载荷（MPC）的定义，操作中在定义刚性区或远端载荷时避免选择不必要的DOF自由度，以消除过约束。

2、error：element type 1 is PLANE42，which can't be used with the VMES command，meshing of volume 3 aborted。

单元类型1是PLANE42，不能使用命令VMES划分体网格，划分体3中止。

解决方法：修改单元类型为适合体网格的单元类型，如solid、shell等；使用AMESH。

3、error:keypoint 10 is referenced by only one line. Improperly connected line set for AL command。

关键点10只在一条线上。

不适合使用AL命令连接线。

解决方法：AL命令是用线来定义面，而选择两条线可能只有两个关键点，因为关键点10不在线上，而定义面至少有三个点，因此，需要再选一条线。

4、Element type 1 is Solid95,which can not be used with the AMES command，meshing of area 2 aborted。

这是因为不同单元类型对应不同的划分网格操作。

上面的错误是因为单元类型为Solid95（实体单元），不能用AMES命令划分面网格。

5、Shear modulus must be positive for material 1 in element 1。

ANSYS的帮助文件使用说明很多网友都曾觉得ANSYS使用起来有一定的难度，经常会遇到这样或那样的问题，但市面上的参考书又不尽如人意，那究竟有没有比较好的参数书？有的，个人认为ANSYS的帮助文件就是一本不错的参数书。

接下来就ANSYS在线帮助的使用做一些基本的介绍，希望能对初学者有所帮助。

ANSYS的帮助文件包括所有ANSYS命令解释及所有的GUI解释，还包括ANSYS各模块的分析指南，实例练习等。

一．进入帮助系统可以通过下列三种方式进入:1.进入ANSYS的操作界面后，在应用菜单中选取Help进入；2.在ANSYS程序组中选取Help System进入：Start Menu > Programs > ANSYS XX>Help System；3.在任何对话框中选取Help。

二．帮助系统的内容安排：点击帮助系统的目录，就看到如下的ANSYS帮助系统的整体内容安排：1．前面4个部分是与软件版本，安装，注册相关的信息，只需作相应的了解即可，如下：※Release Notes※ANSYS Installation and Configuration Guide for UNIX※ANSYS Installation and Configuration Guide for Windows※ANSYS, Inc. Licensing Guide2．接下来两个部分是比较重要的部分，ANSYS的命令和单元手册，对用到的命令和单元应作详细的了解和掌握。

※ANSYS Commands Reference※ANSYS Element Reference3．下面四个部分是ANSYS相关的操作手册，说明如下：※Operations Guide 基本界面，操作指南※Basic Analysis Procedures Guide 基础分析指南※Advanced Analysis Techniques Guide 高级分析指南※Modeling and Meshing Guide 建模与分网指南4．以下几个部分则是ANSYS分模块的分析指南，如下：※Structural Analysis Guide 结构分析指南※Thermal Analysis Guide 热分析指南※CFD FLOTRAN Analysis Guide 流体分析指南※Electromagnetic Field Analysis Guide 电磁场分析指南※Coupled-Field Analysis Guide 耦合场分析指南5．为更好的使用ANSYS方便，快捷的解决更多的工程实际问题，建议仔细学习以下几个部分：※APDL Programmer's Guide：APDL操作手册※ANSYS Troubleshooting Guide：ANSYS错误信息指南※Mechanical Toolbar：机械工具栏※ANSYS/LS-DYNA User's Guide：ANSYS/LS-DYNA操作指南※ANSYS Connection Users Guide：接口技术指南6．欲快速掌握ANSYS的使用，莫过于通过实例和练习，而ANSYS 的帮助系统中则提供大量的例题及练习供用户参考，所以以下两个部分是经常光顾的。

ansys错误及解决⽅法汇总原因分析：这是由于proe的许可⽂件错误导致的提⽰，只要点击ok，proe将会⾃动关闭。

重启打开还是⼀样。

究竟如何解决呢，考虑到开始proe软件可以正常运⾏，经过⼀段时间后出现-1错误，其原因是：移动或删除了许可证⽂件的.，从⽽导致⽆法正常找到许可证⽂件。

解决⽅法：⽅法⼀：如果删除了许可证⽂件我们需要再创建⼀个替换完整的许可证⽂件，如果只是移动了许可证⽂件的位置，我们只需要双击运⾏proe安装⽬录下的C/D/E:\PROE\proeWildfire4.0\bin\ptcsetup.bat（我的是D:\PROE\proeWildfire 4.0\bin），当提⽰添加许可证的时候浏览新的许可证路径加进去即可。

⽅法⼆：更简单的⽅法是不⽤运⾏ptcsetup.bat直接修改以下⽂件即可：⽤记事本⽅式打开bin⽬录下proe1.psf，找到“ENV=PTC_D_LICENSE_FILE”字符串，修改“=”号后⾯的路径即可（这个路径是新指定的proe许可证⽂件路径），如下图所⽰：⽅法三：按步骤操作⼯具/原料：proe完整安装包1、打开运⾏安装包的setup.exe⽂件；2、另外打开安装包或安装路径下的crack⽂件夹，找到license.dat然后使⽤记事本的⽅式打开它；3、把记事本⾥⾯的“00-00-00-00-00-00”全部替换为setup.exe⾸页的ptc主机id，不⽤区分字母⼤⼩写。

替换⽅法：ctrl+H调出替换对话框，填写完成，点击全部替换。

4、替换完成，另存为c盘。

覆盖原⽂件；5、从crack⽂件夹复制三个⽂件再次破解。

1.复制proe_WF5_Win32_crk.exe⽂件到C:\ProgramFiles\PTC\CreoElements\Pro5.0\i486_nt\obj并执⾏。

2.复制proe_mech_WF5_Win32_#1_crk.exe⽂件到C:\Program Files\PTC\Creo Elements\Pro5.0\mech\i486_nt\bin并执⾏。

ESYS is not valid for line element.原因：是由于我使用 LATT的时候，把“-- 〞的那个不小心填成了“1〞。

经过 ANSYS的命令手册里说那是没适用的工程，但是依照我的理解，这些所谓的没适用的工程实质上都是 ANSYS在为后续的版本留接口。

关于 LATT，实质上那个工程可能就是单元坐标系的设置。

当我发现原因后，把 1 改成 0——即使用全局直角坐标系，就没有WARNING了。

自然，直接空白也没有问题。

使用 *TREAD的时候，有的时候显然看文件好好的，但是却出现*TREAD end-of-file in data read.今后认真检查，发现我 TXT的数据文件里，分开是采用 TAB键分开的。

但是在最后一列后边，若是把鼠标点上去，发现数据后边还有一个空格键。

于是，我把每个列最后多的空格键删除，尔后发现上边的信息就没有了。

Coefficient ratio exceeds 1.0e8 - Check results.这个大概是跟收敛相关，但是我找不到详尽的原因。

我建立的一个桥梁解析模型，尽管我解析的结果完满吻合我的力学看法判断，规律完满吻合根本规律，数据也根本吻合实质察看，但是却还是不断出现这个警告信息。

*TREAD end-of-file in data readtxt中的表格数据不完满！No *CREATE for *END. The *END command is ignored忘了写 *END了吧，呵呵Keypoint 1 is referenced by only one line. Improperlyconnected line set for AL command两条线不共点 , 试一试 nummrg 命令。

L1 is not a recognized PREP7 command, abbreviation, ormacro. This command will be ignored还没有进入 prep7 ，先： /prep7Keypoint 2 belongs to line 4 and cannot be moved要点点 2 属于线 4，搬动初级体素时先搬动高级体素！Shape testing revealed that 32 of the 640 new or modifiedelementsviolate shape warning limits. To review test results,please see theoutput file or issue the CHECK command.单元形状奇异，在我的模型中 6 面体单元的三个边长差距较大，可忽略该错误用命令流建模的时候遇到的The drag direction (from the keypoint on drag line 27 thatis closestto a keypoint KP of the given area 95) is orthogonal to theareanormal at that KP. Area cannot be dragged by the VDRAG command.意思是拉伸源面的法向与拉伸路径垂直，不能够使用 VDRAG命令出现的环境ASEL,S,LOC,Z,143e-3VDRAG,ALL, , , , , ,27本意是按地址 z=143e-3 地址的面，尔后沿编号27 的线拉伸，出错，以前用该语句没有任何问题。

ANSYS导入proe之part档的问题为了保证上述两种软件的版木兼容，Pro/E的版本不得高于同期的AnsyS的版本:同时要安装ansys里的和proe接口模块！ansys安装程序里已经有了不需要下载。

(l)在开始程序下运行Ansys，选择utilities下的ans_admin项，在ans_dmin 弹出图框中选择configuration options，在下一个confirguration options弹出图框中选择configuration connection for pro/E，在configure ansys connection for pro/E中的ansys product中选择ansys multip，在graphicsdevice name中选择win32，在出现SuccesS 图框中记下config.anscon文件位置。

在出现的Pro/Einstallationinformation下的Pro/Einstallationpath中填入安装Pro/E的路径。

在language used with Pro/E中选择语言usa，最后将记录下的config.anscon拷贝到Pro/E的安装目录下。

这样就可以将Pro/E的模型直接传到Ansys中了。

同时应注意在Pro/E中建立的模型应予存盘.设置好以后重气计算机！在proe菜单栏里就有ansys菜单了！在proe里建好模型点ansys菜单就可以在proe里启动ansys 找到proe工作目录下的.anf文件！从ansys里读入那个文件在执行plot画图命令就可以把proe里建的模型导入到ansys里了！我用的是ansys8.0和proe野火2.0 成功关联.大家好像对ANSYS导入proe之part档的问题一直没有很好的解决，在此我把我的方法给大家。

1) 在同机的同一操作系统下安装有Pro/E和ANSYS两种软件；2) 保证上述两种软件的版本兼容，Pro/E的版本不得高于同期的ANSYS的版本；我的是ANSYS8.1 PROE20013) 开始－选择ANSYS－unitilities－ANS_ADMIN－Configuration Connection for Pro/E?－OK?－Configuration options?Utility Work space in?选择Graphics device name(NT: Win32)?Product 给出Language used with?给出Pro/Engineer installation path 如"e:\proe2001"- OK；?Pro/Engineer:usascii4) 运行Pro/Engineer并配置config.pro；名称值说明fem_ansys_annotations yes 输出“模拟”分析名为ANSYS中的注释。

完整的安装文件如下，其中crack 文件夹下有两个文件夹。

2.2 安装前注意事项安装前建议先关闭360 等杀毒软件，因为如果设置防毒等级较高的话，可能安装中有的命令它自动阻止了，虽然一般情况下没问题。

下载和安装路径都要用英文，而且今后使用中ANSYS 的文件名最好也用英文，貌似它还不支持中文。

本教程操作系统为windows 8.1 x64专业版。

相信32 位系统中安装过程也类似。

2.3 用虚拟光驱加载安装光盘下载并安装虚拟光驱【推荐精灵虚拟光驱(Daemon Lite Tools) ，下载地址为打开虚拟光驱，点击界面中间的"添加DT 虚拟光驱"，如果之前使用过，界面中将本身就存在一个光驱的盘符，例如J:。

这样界面最底下将出现两个光盘盘符H:和J:。

再点击最左侧的"添加映像"，在弹出的"打开"对话框中选择Disk1和Disk2，然后确定。

然后在映像目录选择Disk1，右键选择载入到H:盘。

之后我们看到界面左下角的H 盘已经显示为一个黄底黑字的A 的图像，表示Disk 1 已经成功加载了。

同理，进行相同的操作，在映像目录选择Disk2，右键选择载入到J:盘。

两个安装盘都加载成功后，虚拟光驱的界面应如下图：最下侧的文件都将显示有两个光盘。

如果不是这样，请重新添加。

这时在"计算机"目录下会看到这样的显示，说明两个安装光盘已经可以按照正常硬盘分区打开。

安装ANSYS Product产品主程序打开DISK1，以管理员身份运行"reReqCheck"文件，程序将会检查你还需要安装所必须的组件。

【下文如果没说明，各程序都是以管理员身份运行。

】如果显示你还需要安装其它组件，那么运行"InstallPreReqs"，它会自动帮你安装相应组件。

提示全都安装完成之后，可以再检查一下。

当然，肯定可以直接运行"InstallPreReqs"安装各组件啦。
