PSCAD_Matlab_2Faults

从CAD图形到matlab的自动转化。可以转换STL文档，已实现从AutoCAD和pro-E到matlab的转换(CAD2MATDEMO, a demonstration of importing 3D CAD data into Matlab. To get CAD data into Matlab, the process is: 1) Export the 3D CAD data as an ASCII STL (or Pro/E render SLP) file. 2) This Matlab routine reads the CAD data Once read, the CAD data is rotated around a bit. Program has been tested with: AutoCAD, Cadkey, and Pro/Engineer.Should work with most any CAD programs that can export STL. )

ADINA 系统是一个单机系统的程序，用于进行固体、结构、流体以及结构相互作用的流体流动的复杂有限元分析。借助 ADINA 系统，用户无需使用一套有限元程序进行线性动态与静态的结构分析，而用另外的程序进行非线性结构分析，再用其他基于流量的有限元程序进行流体流动分析。此外， ADINA 系统还是最主要的、用于结构相互作用的流体流动的完全耦合分析程序（多物理场）。(ADINA System is a stand-alone system program for performing complex fluid flow finite element solid structure, and fluid structure interaction analysis. With ADINA system, users do not need to use a finite element program linear static and dynamic structural analysis, but with additional nonlinear structural analysis program, and then the other program flow based on finite element analysis of fluid flow. In addition, ADINA system or main, fully coupled analysis program for fluid flow structure interaction (multi-physics).)

》模块清晰，注释明了 》计算了圆柱的拉力系数，与现有文献吻合很好 》圆柱边界条件采用了两种，1 标准反弹；2 半步长反弹(1 Code is in a clear modular design with detailed comments. 2 Drag coefficient of cylinder wae computed agreed very well with the reference. 3 Standard and half-way bounce-back schemes are applied to the nodes around the cylinder separately.)

金属材料的随动强化有限元模型，适用于有限元分析的本构模型二次开发(Finite element model of kinematic hardening of metallic materials, constitutive model suitable for finite element analysis of secondary development)

考虑混沌效应的粒子群算法，比常规粒子群更容易跳出局部解(optimization method of PSO, concerning the Chaos effect.)

有限元求解柏松方程。本文采用FORTRAN语言编制程序。程序中大部分变量采用有名公共区存储方式存储，这样可以减少内存占用量。 IFG：生成有限元网格信息，即元素节点局部编码与总体编码对照表，节点实际坐标，边界节点编码与边界点上的已知值 GKD：生成总刚一维存储对角元的地址，计算总刚一维存储长度 FIXP：设置已知节点函数值 GK(NI,NJ,ADJ,AIJ)：单元刚度矩阵计算 GF(NI,N,M,LE,YI,FE)：单元列阵的计算 AK(I,J,AIJ)：总刚度矩阵元素迭加 QEB：总刚度矩阵和总列阵合成 BDE：边界条件处理 SOLGS：Gauss-Seidel迭代法求解方程组 UDIFF(NI,NFLAG,UDIF,LE,ADJ)：标准元素内形状函数导数计算 DIFF：节点上 ， 加权平均 (In this program, FEM was used to solve the possion equation. It is implemented through FORTRAN)

几何造型库OpenCASCADE自带的例子,可以导入导出IGES/STEP格式的CAD文件,增加了用qtcreator打开工程文件的脚本文件(Geometric modeling library OpenCASCADE own example, you can import and export IGES/STEP format CAD files, increasing the use qtcreator script file to open the project file)
