平面问题三角形单元有限元程序，VB源码。有较好的可视化界面-Plane problem triangular element finite element program, VB source code. Have better visual interface

工程中有限元方法应用，先用MSC.Patran进行模拟与仿真，再利用VB程序代码进行对比验证（基于一些案例）-Engineering Finite Element Method, first with MSC.Patran simulation and simulation, reuse VB code comparison verification (based on the number of cases)
