patran使用技巧

分享patran使用中的一些技巧patran技巧[分享]为何我的FEM选单中不会出现Hybrid Mesh<Patran> 为何我的FEM选单中不会出现Hybrid Mesh?-->请在系统的环境变数中增加以下变数:PATRAN_USE_HYBRID_SURFACE_MESHER值设定为TRUE ,这样在surface mesh处, 除了Iso Mesh跟Paver Mesh外,就会看到另外一个Hybrid Mesh的选项[分享]MSC多解析任务批处理的方法如果仅有一台机器可以进行解析运算,有时候任务比较多的时候会时间来不及.提交模型让机器计算之后只能在旁边傻看着,什么也做不了. 其实有一种比较好一点的方法.可以用批处理文件让机器连续自动处理,下班时运行披处理文件,第二天早上来看结果.方法如下:比如有3个模型,S1.MOD,S2.MOD,S3.MOD1. 分别将上诉3个模型导出为DAT文件2.建立批处理c:\mscvn4w2002\solver\bin\nastran S1.datc:\mscvn4w2002\solver\bin\nastran S2.datc:\mscvn4w2002\solver\bin\nastran S3.dat3. 双击4. 下班5. 上班6. 导入解析结果.[转帖]PATRAN的一些小技巧1、在Patran里如何Move 一组Points 的位置, 而不改变这组Points 的ID 编号? Group/Transform/Translate的功能,这样不但编号不会变, 连property跟边界条件都会保留2、Patran如何执行多次Undo?所有Patran的操作步骤, 都记录在最新的一个patran.ses.xx中,如果需要多次undo, 可以刪除最后不需要的步骤指令行,再利用File -> Session -> Play 的方式, 执行改过的patran.ses.xx ,这样可以无限制的undo。

The ui_write functions writetext to the history window, the session file(patran.ses.##), and the journal file(model.db.jou)Exercise 2: Hello World!Write and execute a PCL function that accepts a single real number argument and echoesHello World, my favorite number is ….to the MSC.Patran session file and history window.Your function will use either the ui_write(…),ui_writef(…), or ui_writec(…) functions.If you use the ui_writef(…) and ui_writec(…) functions, refer to the documentation for the correct format specifiers.Extra credit: How would this function change if you wanted to echo your favorite 10 numbers to the session file? Extra credit: How would this function change if you wanted to echo your favorite color to the session file?Exercise 3: Effective PCLWrite an essay on how the effective use of PCL could:a) Help create a lasting world peaceb) Eliminate world hungerc) Conquer the common coldd) Stop global warmingExtra credit: How could PCL be used to find Elvis?PCL OperatorsExamplesDist = mth_sqrt((x2-x1)**2 + (y2-y1)**2 + (z2-z1)**2) MyString3 = MyString2//”hijk”IF (a == b) THEN c = dIF (a == b && a == c) THEN ui_write(“Equilibrium”)x += 1 (this is equivalent to x = x +1)String comparisons❑The string comparison operators are special in that they ignore trailing blanks and uppercase and lowercase. Therefore, all of the following expressions are TRUE“ABC” == “ABC ““ABC” == “abc”❑Leading blanks are compared, i.e., “TEST” != “ TEST”❑To perform case sensitive comparisons use the str_equal() function, i.e.,IF (str_equal(GroupName1, GroupName2)) THEN RETURN 0PCL Variables and Constants Datatypes❑LOGICAL Boolean value: TRUE or FALSELOGICAL done, created31-1)❑INTEGER Value between +/- (2INTEGER i, num_nodes, node_id❑REAL Single precision floating value between 1.0E-30 and1.0E+30 (positive or negative)REAL x, y, z, force, pressure❑STRING Character string surrounded by double quotes, “Have you seen Elvis?”.

patran使用技巧

patran学习-推荐下载

Introduction这篇文章我本人在学习patran/natran 过程中遇到的问题，及后来找到的解决方法，这篇文章也在逐步更新中，希望这篇文档能给那些学习用patran/nastran 的一点帮助。

Yuanchongxin Delft2011/10/3111. THE SOLUTION FOR THE RESIDUAL STRUCTURE AND THE APPLIED LOADS FOR THE CURRENT SUBCASE ARE ZERO.后来将边界条件由１２３４５６改为１２３，即将位移约束变成simplified supported，就没有此问题了。

2. USER WARNING MESSAGE 4124 (IFS3P)THE SPCADD OR MPCADD UNION CONSISTS OF A SINGLE SET 在图中用了RB3 的MPC，其中dependent node (ux,uy,uz), independent(ux,uy,uz,rx,ry,rz),有可能是这里的问题。

不过这个倒不影响计算结果。

3. 建立夹层结构的有限元网络对于meshing, sweep can produce the solid element on the basis of the shell element. 另外sweep 下的loft，可以在两个shell mesh 之间，创建solid element. 对于夹层结构的modeling, shell and solid element should share common node. 否则算出来的结果，solid stress 为零。

至于如何共用节点，则需用到element 下的sweep 命令。

4. No PARAM values were set in the Control File不管失败还是成功的f06 文件中，都会出现这句话。

2）读入分析结果：Action→Accese Results，Object→attach XDB，Method→Results Entities，单击 Select Results File，选择文件名→mode9-1.xdb，OK，Apply。这一步骤，是将 Nastran 的分析结果读入到 Patran 中来，这样才可以进行后处理。
2）读入分析结果：Action→Accese Results，Object→attach XDB，Method→Results Entities，Select Results File…→mode9-1.xdb，OK，Apply。 3．后处理，
各阶模态的频率：在 Select Result Cases ቤተ መጻሕፍቲ ባይዱ，会列出结构的各阶频率，如图所示。

5．定义各向同性的铝材料 1）定义材料：Action→Create，Object→Isotropic，Method→Manual Input，Material Name→
aluminium，Input Properties…，Constitutive Model→Linear Elastic，Elastic Modulus→70000，Poisson Ratio→0.3，OK，Apply。这里，创建了各向同性的铝材料，手工输入了杨氏模量和泊松比，对于各向同性材料的静态分析，材料的独立弹性常数只有两个，也不必输入材料的密度值。
8．后处理， 1）显示位移云纹图：Action→Create，Object→Quick Plot，Select Result Cases→Default Static
Subcase，Select Fringe Result→Displacements Translational，Quantity→Magnitude，Apply。此时，平板模型的位移云纹图就显示出来，如图 9-1-3 所示。

patran安装说明补充

patran安装说明补充patran2021+nastran2021安装（我是win7旗舰版32位系统）都是iso文件，使用虚拟光驱daemontoolslite打开安装方法如下：2.新建环境变量，计算机右键属性->（左边栏）高级系统设置->高级->环境变量->用户变量->新建->变量名为“lm_license_file”。

变量值为“1700@计算机名”，比如说我的计算机名就是\局部变量就是1700@abc。

计算机名可以从右键计算机属性中搜到。

3.生成license.dat文件。

（光驱盘符假设为g）将g(patran2021):\\magnitude下的msc_calc.exe文件拷贝到任意目录，推荐放在桌面上，运行msc_calc.exe，会在当前目录下生成一个license.dat文件。

这个文件备用。

4.加装licensing。

运转g(patran2021):\\magnitude目录下的msc.licensing_11.6_windows.exe，当被问到挑选一个license文件的时候挑选出上一步分解成的license.dat文件，稳步直至顺利完成。

特别注意：a右键以管理员身份安装license以及软件！b在加装license时，提示信息你的hostid时特别注意比对其与否与a中揭发的物理地址一致！若不一致,可能将就是无线网络的mac地址而非本机的mac地址，此时须要停止使用无线网络，再重新安装licensec检查license目录下的license.dat文件第一行与否为：serve计算机名物理地址17005.证实license与否需用以及“服务”与否关上。

从开始菜单中找出刚才加装的msc.software>msc.licensing11.6中的flexlmconfigurationutility，打开，点取configservices标签，把最下面的startserveratpowerup和useservices点上勾，再点取saveservices。

菜单和工具栏区如图1-2所示,patran 的界面上有一行菜单，两行工具栏。

图1-2 菜单工具栏Patran 的菜单是该软件的重要组成部分，使用菜单项，可以完成多设置和操作。

本来，菜单与各种工具是配合使用的，两者是不能独立区分的。

这里对菜单栏进行简单的介绍,一般情况下，Patran 有九个主菜单项,如图1-2所示，文件管菜单栏应用菜单按钮工具栏理(File）菜单主要用于Patran数据库文件的打开/关闭,同时也用来从其他CAD系统输入模型;组（Group)菜单主要用于组的操作，作用类似CAD系统中的“层"；视窗管理（Viewport)菜单用于视窗设置;视图操作（Viewing）菜单用于图形显示设置,包括了工具栏中一些工具的功能；元素显示管理（Display)菜单用于设置各种元素的显示方式；参数设置（Preferences）菜单用于选择求解器,定制用户自己的环境等操作；工具选项（Tools)菜单中提供了许多非常有用的工具；在线帮助(Help）菜单为使用者提供在线帮助.工具栏各工具功能见表一：表一 Patran工具栏各工具功能列表2。
