摘要
介绍了参数化有限元分析(PFEA)的概念和内容,提出了参数化网格划分的概念。详细阐述了通过参数化网格划分来建立有限元模型的途径;研究了参数化网格划分的具体内容和实现方法;给出了在Uni-graphics(UG)上实现参数化网格划分的工作流程。通过编程,在UG上开发了基于历史的曲面参数化网格划分系统——ParaMesh,实现了对曲面的参数化网格划分,并给出了若干参数化网格划分的实例。
The conception and content of parameterized finite element analysis（for short PFEA） were introduced. Based on the requests of PFEA, the conception of parameterized mesh was presented The approach of establishing finite element model by parameterized mesh was elaborated The content and realization method of parameterized mesh were researched herein. Simultaneously, the process to realize parameterized mesh on Unigraphics（for short UG） software was proposed And by programming, ParaMesh system the parameterized mesh system based on history was developed, the parameterized mesh in the surface was realized. At last, several examples on parameterized mesh are provided.
