摘要
提出了一种空间有限元网格的自动生成算法。首先利用体元—等分线的相交关系找出空间任一实体的中面 ,然后利用中面将实体划分成可再剖分的点、边、面子区域 ,再利用中点剖分法将这些子区域剖分成六面体 ,最后利用超穷映射的方法将这些六面体划分成最终的有限元网格。
An algorithm of automatic three dimension finite element mesh generation is presented in this paper.First,the medial surface of a solid is found by the voxel bisector intersection relations,second,the solid is subdivided into some vertex、edges、faces subregions by the medial surface,then these subregions are subdivided into hexahedron by the midpoint subdivision,finally these hexahedrons are subdivided into the final elements by the transfinite mapping.
