有限元数据前处理的探讨

The Discussion of Data Pro-handling for Finite Elements

本文将有限元计算域划分为若干个子域。对于每个子域进行计算网格的自动剖分。探讨了二维计算域的三角形线性元和二次元、四边形线性元和二次元的网格自动生成技术并利用计算机的图形显示技术动态地显示出计算域的分区情况与网格图形。文中方法概念清晰,原理简单,效率较高。

In this paper, the calculative region of finite elements is divided into several Sub-regions. in which the calcutative meshes, can be generated automatically. Th technic of the automatic generation of meshes, which used for the constant strain element (such as 3- node triangle and 4- node rectangle element) and linear strain elemerit (such as 6-node triangle and 8- node rectangle), is discussed. The sub-regions and net of the calculative region can be displayed dynamically by using the technic of computer graphics. The method used in this paper is clear in conception. simple in principles, and ore effi- cient.
