摘要
本文对四节点四边形有限元网格系统的自动生成进行了深入研究。立足前人工作的基础,为解决区域的自动划分、复杂边界区域的整域一次生成、多连通域网格自动生成等问题,提出了“分段逐层生成”的新算法。进一步提高了网格再划分系统的实用性。
In this paper the generation method for 4- node-quadrilateral element is deeply studied. Based on the work done by formers, and in order to solve the problems such as automatic zone-dividing ,intergral generation for the zone which has a complex boundary,artomatic generation for multiply connected domain,a new algorithm is given. The new algorithm improved the validity of the system.
