摘要
本文提出了一种三维网格自动生成的方法,并采用FORTRAN算法语言,编制了三维20节点等参元网格自动部分的通用计算程序,它适用于复杂形状或具有多种介质区域以及复连域问题的多步或迭代分析,对三维有限元具有较高的实用价值。
A self-organizing mesh generation programming for 3-D isoparametric element problems is presented. Using FORTRAN-77 algorithmic language,a general program for 3-D, 20-node isoparametric element is developed, which is applicable to the stepped or iterative analysis of problems involving complicated configuration. Because of its simplicity and flexibility,this program has considerable practical value in 3-D Finite Element Calculation.
