摘要
介绍了一种能够适用于任意平面图形的四边形有限元剖分方法 ,该方法基于组合放大思想 ,其基本原理是将不同层次的小正方形进行组合 ,得到一系列较高层次的大正方形 ,用该法得到的单元除在边界因需要满足边界要求外 ,其它地方的单元质量很好 ,文章利用该方法对一实际平面图形进行了四边形剖分 ,结果表明本方法是优于其他剖分方法的。
A quadrilateral finite element meshing method fo r any 2-D arbitrary area was discussed in detail.The method is based on princ iple of construction,which transforms quadrilateral element in different layer t o higher one,elements produced by this method except those which are adjacent to edge have high quality.In the end,a sample area was meshed,the result proves th at this method is more effective than other ones
