摘要
剖分是进行有限元计算的前期工作 ,它主要是通过网格化 ,将实体划分成具有相同类型的单元。本文采用由外向内的剖分思路 ,利用 10节点四面体等参数单元 ,实现了对三维不对称实体的网格剖分。计算结果表明 ,使用本文的剖分算法进行后期的有限元计算是十分理想的。
Dissection is the prophase work of FEM analysis, which disparts studied body to the similar type elements through carving up the nets. In the present paper, 10 nodes tetrahedron isoparametric element was employed to perform the net dissection of asymmetry entity through unusual dissection idea. The computing result shows that it is very pretty to use this algorithm in the follow finite element calculating.
