摘要
介绍一种将线段转换成三维六面体有限元网格的实用方法。根据各线段的拓扑关系形成由无向边组成的四边形面 ,由面的邻接关系生成无编号规则的六面体 ,引入局部坐标系并调整各六面体顶点的排列顺序使其成为符合有限元编号规则的六面体单元。该方法被应用于可视化通用结构分析系统 VSES中 ,取得了满意的效果 ,速度快、稳定性好。
A practical method of generating hexahedron mesh for finite element method through transfering lines into volumes was introduced. Quadrangle faces with no direction sides were firstly formed based on the topology relation of lines, then hexahedrons which had no serial number rule were built according to the adjacency relation of the quadrangle faces. Finally, the hexahedrons were transferred into hexahedron elements which were satisfied the serial number rules in FEM by adjusting the order of the nodes' number. The application in the system VSES showed that the method was feasible and effective, and it has some advantages such as rapid speed, extensive applicability and etc.
