本文对四节点四边形有限元网格的自动生成方法进行了深入地研究,提出了一种适用于塑性成形问题分析的由边界向域内逐层生成的四边形有限元网格自动划分方法。就该方法的具体技术、算法进行了研讨,并给出了实例。
In this paper, the method of automatic generation of four-node quadrilateral finite element mesh is studied in detail. A new method of automatic quadrilateral finite element mesh generation is proposed, which is suitable for plastic forming analysis. The specific techniques and algorithms of this method are discussed and examples are given.
