基于DELPHI的MSC.Marc三维有限元参数化建模

Parameterized Three-Dimensional Finite Element Modeling of MSC.Marc Based on DELPHI

文章介绍了基于DELPHI的MSC.Marc三维有限元参数化模型的建立过程,并以赫兹接触问题为例描述了其基本思路及其实现方法。文中参数化建模过程采用的方法是利用DELPHI程序把所有前后处理过程均写入一个“命令流”文件脚本,然后一次性提交有限元求解器执行,实现编程式参数化。实例分析结果与理论解一致,表明参数化有限元建模更简便,能大大提高求解效率。

This paper introduced the process of the parameterized three-dimensional finite element modeling of MSC.Marc based on DELPHI, and the basic process and method was showed by the example of the analysis of HZ contact. The idea adopted in the process of parameterized modeling is to write all the process into a script document of instruction stream, and then submit it to the FEA processor in a lump. The parameterized modeling by programming was carried out. The results of the FEA analysis accorded with the results of theory, which shows that the parameterized finite element modeling is simpler than common modeling and the efficiency of solving finite element analysis problems is improved greatly.
