摘要
提出了一种新的四边形有限元网格的生成方法基区拼合法。在基区划分的基础上 ,先进行基区内部的网格生成 ,然后把各个基区缝合起来 ,形成完整的有限元网格。该方法简单且行之有效 ,特别适用于解决轮廓形状不太复杂的二维问题。
A new memod on quadrilateral FEM mesh generation,i.e.basic areal inking method,is advanced here.Firstly a contour shape is divided into several basic areas,and regular mesh is generated inside.Then the various areas are combinated into a complete mesh system.This method is easy and effective and it is suitable in particular for solving those two dimension problems with less complex contour shape.
