摘要
介绍了一个基于几何造型系统的有限元分析前置处理系统.其主要功能是对几何造型系统的NURBS曲面以及二维任意形体有限元网格划分.该系统可作为几何造型系统与有限元分析程序之间的接口.
A preprocessing system of finite element analysis based on geometrical modelling is introduced.The function of this preprocessing system is generating finite element mesh from NURBS surface and 2D object produced by geometrical modelling system.This preprocessing system can be used as an interface between geometrical modelling system and finite element analysis program.
