| 摘 要： | 本文讨论了有关三维有限元前处理的一些问题。采用以等参映射为基础的自动编码方法,可自动剖分20节点六面体和15节点五面体及其混合单元。对矩阵带宽极小化的Rosen算法作了一些改进。为了数据检查,绘制了消除了隐线的三维网格图,它可为计算和分析提供方便。

| Abstract: | This paper deals with the preprocessing of finite element analysis for 3D solids. Adopting automatic encoding method based on isoparametric mapping, it is possible to dissect given solid automatically into a number of hexahedrons with 20 nodes or pentahedrons with 15 nodes or their combinations. The Rosen's algorithm is improved for minimizing the matrix bandwidth. Besides, an axonometrie projection of 3D mesh of the solid with hidden lines eliminated is drawn for data check. |
