NORMALIZED ELEMENT NODE TOPOLOGICAL MATRIX OF FINITE ELEMENT MESHES

On the basis of concept of element node topological analysis, the normalized element node topological matrices for finite element meshes are presented in the paper, including 3-node and 6-node triangular element, 4-node and 8-node quadrilateral element, 8-node and 20-node hexahedral element. It is beneficial to further analyzing topological characteristics of finite element models and automatic generation of meshes

有限元网格图自动生成算法

本文在有限元网格图拓扑分析的基础上,讨论了单元节点拓扑阵自动生成方法和整体节点拓扑阵自动组集方法,并给出了算法。这种方法实现了2D和3D有限元网格图完全自动生成过程,并为单元及节点的相关性分析提供了依据。
