一,写给ansys初学者,如何充分运用ansys的HELP学习ansys,假设说手里只有软件,没有任何的中文图书(其实很多的中文图书就是完全的翻译ansys自带的HELP,而且有些翻译的质量实在是不敢恭维,这里仅说利用ansys自带的HELP).那么我建议以下的这种学习方式,假设你已经有了基本的有限元知识.简易教程中用的是d版ansys9.0sp1.1,养成良好的习惯,每一次的工作都建一个文件夹,并取一个文件名,参看图1.AVI。
或者参看Basic Guide | Chapter 1. Getting Started with ANSYS | 1.2. Building a Model2,首先完成help里面的tutorials,里面有结构学的,电磁学的,热学的,还有流体学的等近十类指南,选择其中的一种或者是两种来做,比如说你是做结构学的,当然就选择结构学的啦,一步步按着指导做下去,以此来熟悉anays的图形操作(GUI).参看图2.AVI学ansys还是要熟悉GUI操作的,每运行一次GUI操作会在ansys的工作目录里面生成一个.LOG文件，适当处理就会得到一个命令流文件，然后可以导入该命令流，就相当于重复了上面的GUI操作（再加入适当的APDL控制语句，就可以以小做大，这是后话，这里先不提），参看图3.avi。
3，看Basic Analysis Guide，建模，加负载，计算，通用后处理，时间后处理的基本用法这里都有了。
图4.avi4,熟悉了基本的操作之后,以后就要看一点命令流了,毕竟命令流效率高,速度快,而且最主要的,ansys高手都在用.Verification Manual，里面给出了264个例子，这是我们的好帮手，一定要熟悉，当然还是要选择自己熟悉的来做。
比如说我是做动力学分析的，就选择一个动力的例子来做。
如图5.avi.这些我觉得是非常非常有用的。
在这里你要熟悉里面的命令是什么意思，就得一条条查查了，好在里面的许多命令都是英文的缩写，大多可以猜出是什么意思来，但许多还是要自己查的。
ansys案例Ansys案例。
在工程领域，Ansys是一个非常重要的工具，它可以用来进行有限元分析，对结构、流体、热传导等进行模拟，帮助工程师们更好地设计和优化产品。
下面我们将介绍一个Ansys案例，来看看它是如何应用于实际工程问题中的。
我们选取了一个汽车发动机的热传导分析作为案例。
汽车发动机在工作时会产生大量的热量，如果散热不好，就会导致发动机过热，甚至损坏。
因此，对发动机的热传导特性进行分析非常重要。
首先，我们需要建立发动机的三维模型，并对其进行网格划分。
Ansys提供了强大的建模和网格划分工具，可以快速准确地完成这一步骤。
接下来，我们需要定义材料的热传导性质，包括导热系数、比热容等参数。
这些参数对于模拟结果的准确性至关重要。
然后，我们需要设置边界条件和加载条件。
在这个案例中，发动机的外表面会受到空气的冷却，因此我们需要定义外表面的对流换热系数。
同时，发动机内部会有燃烧产生的热量，需要通过内部表面来定义热源。
这些边界条件和加载条件的设置也是Ansys的一大特色，用户可以根据实际情况进行灵活定义。
完成了前期的准备工作后，我们就可以进行热传导分析了。
Ansys会对整个发动机进行数值求解，得到温度场的分布情况。
通过分析温度场，我们可以看出发动机的哪些部位温度较高，哪些部位温度较低，从而找出散热不良的部位。
通过这个案例，我们可以看到Ansys在工程领域的强大应用价值。
它不仅可以帮助工程师们进行复杂的物理场模拟，还可以为工程设计和优化提供重要参考。
当然，Ansys的应用远不止于此，它还可以用于流体动力学分析、结构强度分析等多个领域。
总的来说，Ansys案例的介绍可以帮助我们更好地了解该软件在工程领域的应用，对于工程师们来说，掌握Ansys是非常重要的，它可以帮助他们更好地解决工程问题，提高工作效率，降低成本，提高产品质量。
希望这个案例可以为大家带来一些启发，也希望Ansys在未来能够发挥更大的作用，为工程领域的发展贡献力量。
ANSYS中的超单元从8.0版开始，ANSYS中增加了超单元功能，本文通过一些实际例子，探讨了ANSYS 中超单元的具体使用。
1 使用超单元进行静力分析根据ANSYS帮助文件，使用超单元的过程可以划分为三个阶段(称为Pass)：(1) 生成超单元模型(Generation Pass)(2) 使用超单元数据(Use Pass)(3) 扩展模型(Expansion Pass)以下摘自htbbzzg邹老师博客，请勿乱传!下面以一个例子加以说明：一块板，尺寸为20×40×2，材料为钢，一端固支，另一端承受法向载荷。
首先生成原始模型se_all.db，即按照整个结构进行分析，以便后面与超单元结果进行比较：首先生成两个矩形，尺寸各为20×2。
然后定义单元类型shell63；定义实常数1为： 2 (板厚度)。
材料性能：弹性模量E=201000；波松比μ=0.3；密度ρ=7.8e-9；单位为mm-s-N-MPa。
采用边长1划分单元；一端设置位移约束all，另一端所有(21个)节点各承受Z向力5。
计算模型如下图：静力分析的计算结果如下：为了后面比较的方便，分别给出两个area上的结果：超单元部分，按照上述步骤操作如下：(1) 生成超单元选择后半段作为超单元，前半段作为非超单元(主单元)。
按照ANSYS使用超单元的要求，超单元与非超单元部分的界面节点必须一致(重合)，且最好分别的节点编号也相同，否则需要分别对各节点对建立耦合方程，操作比较麻烦。
实际上，利用ANSYS中提供的mesh200单元，对超单元和非超单元的界面实体，按照同一顺序，先于所有其它实体划分单元，很容易满足界面节点编号相同的要求。
对于多级超单元的情况，则还要结合其它操作(如偏移节点号等)以满足这一要求。
对于本例，采用另一办法，即先建立整个模型，然后再划分超单元和非超单元。
即：将上述模型分别存为se_1.db (超单元部分)和se_main.db (非超单元部分)两个文件，然后分别处理。

Problem DescriptionThis is a simple, single load step, structural static analysis of the corner angle bracket shown below. The upper left-hand pin hole is constrained (welded) around its entire circumference, and a tapered pressure load is applied to the bottom of the lower righthand pin hole. The objective of the problem is to demonstrate the typical ANSYS analysis procedure. The US Customary system of units is used.2.1.2.1. GivenThe dimensions of the corner bracket are shown in the accompanying figure. The bracket is made of A36 steel with a Young’s modulus of 30E6 psi and Poisson’s ratio of .27.2.1.2.2. Approach and AssumptionsAssume plane stress for this analysis. Since the bracket is thin in the z direction (1/2 inch thickness) compared to its x and y dimensions, and since the pressure load acts only in the x-y plane, this is a valid assumption. Your approach is to use solid modeling to generate the 2-D model and automatically mesh it with nodes and elements. (Another alternative in ANSYS is to create the nodes and elements directly.)2.1.2.3.

Exit the ANSYS program.2.1.3. Build GeometryThis is the beginning of Preprocessing.2.1.3.1. Step 1: Define rectangles.There are several ways to create the model geometry within ANSYS, some more convenient than others. The first step is to recognize that you can construct the bracket easily with combinations of rectangles and circle Primitives. Decide where the origin will be located and then define the rectangle and circle primitives relative to that origin. The location of the origin is arbitrary. Here, use the center of the upper left-hand hole. ANSYS does not need to know where the origin is. Simply begin by defining a rectangle relative to that location. In ANSYS, this origin is called the global origin. 1. Main Menu> Preprocessor> Modeling> Create> Areas> Rectangle> By Dimensions 2. Enter the following: X1 = 0 (Note: Press the Tab key between entries) X2 = 6 Y1 = -1 Y2 = 1 3. Apply to create the first rectangle. 4. Enter the following: X1 = 4 X2 = 6 Y1 = -1 Y2 = -3 5. OK to create the second rectangle and close the dialog box.Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates利用 pdfFactory Pro 测试版本创建的PDF文档 Introductory Tutorials Page: 42.1.3.2. Step 2: Change plot controls and replot.The area plot shows both rectangles, which are areas, in the same color. To more clearly distinguish between areas, turn on area numbers and colors. The "Plot Numbering Controls" dialog box on the Utility Menu controls how items are displayed in the Graphics Window. By default, a "replot" is automatically performed upon execution of the dialog box. The replot operation will repeat the last plotting operation that occurred (in this case, an area plot). 1. Utility Menu> Plot Ctrls> Numbering 2. Turn on area numbers. 3. OK to change controls, close the dialog box, and replot.Before going to the next step, save the work you have done so far. ANSYS stores any input data in memory to the ANSYS database. To save that database to a file, use the SAVE operation, available as a tool on the Toolbar. ANSYS names the database file using the format jobname.db . If you started ANSYS using the product launcher, you can specify a jobname at that point (the default jobname is file). You can check the current jobname at any time by choosing Utility Menu> List> Status> Global Status. You can also save the database at specific milestone points in the analysis (such as after the model is complete, or after the model is meshed) by choosing Utility Menu> File> Save As and specifying different jobnames (model.db, or mesh.db, etc.). It is important to do an occasional save so that if you make a mistake, you can restore the model from the last saved state. You restore the model using the RESUME operation, also available on the Toolbar. (You can also find SAVE and RESUME on the Utility Menu, under File.) 4. Toolbar: SAVE_DB.2.1.3.3. Step 3: Change working plane to polar and create first circle.The next step in the model construction is to create the half circle at each end of the bracket. You will actually create a full circle on each end and then combine the circles and rectangles with a Boolean "add" operation (discussed in step 5.). To create the circles, you will use and display the working plane. You could have shown the working plane as you created the rectangles but it was not necessary.Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates利用 pdfFactory Pro 测试版本创建的PDF文档 Introductory Tutorials Page: 5Before you begin however, first "zoom out" within the Graphics Window so you can see more of the circles as you create them. You do this using the "Pan-Zoom-Rotate" dialog box, a convenient graphics control box you’ll use often in any ANSYS session.1. 2. 3. 4.Utility Menu> PlotCtrls> Pan, Zoom, Rotate Click on small dot once to zoom out. Close dialog box. Utility Menu> WorkPlane> Display Working Plane (toggle on)5. 6. 7. 8. 9.Notice the working plane origin is immediately plotted in the Graphics Window. It is indicated by the WX and WY symbols; right now coincident with the global origin X and Y symbols. Next you will change the WP type to polar, change the snap increment, and display the grid. Utility Menu> WorkPlane> WP Settings Click on Polar. Click on Grid and Triad. Enter .1 for snap increment. OK to define settings and close the dialog box.10. Main Menu> Preprocessor> Modeling> Create> Areas> Circle> Solid Circle Be sure to read prompt before picking. 11. Pick center point at: WP X = 0 (in Graphics Window shown below) WP Y = 0 12.

OK to close picking menu. 14. Toolbar: SAVE_DB.Note: While you are positioning the cursor for picking, the "dynamic" WP X and Y values are displayed in the SolidCircular Area dialog box. Also, as an alternative to picking, you can type these values along with the radius into the dialog box.2.1.3.4. Step 4: Move working plane and create second circle.To create the circle at the other end of the bracket in the same manner, you need to first move the working plane to the origin of the circle. The simplest way to do this without entering number offsets is to move the WP to an average keypoint location by picking the keypoints at the bottom corners of the lower, right rectangle. 1. Utility Menu> WorkPlane> Offset WP to> Keypoints 2. Pick keypoint at lower left corner of rectangle. 3. Pick keypoint at lower right of rectangle.4. OK to close picking menu.5.
