摘要:
在有限元中,把形状复杂的模型划分成四边形或六面体网格,一直以来都是一个很难解决的问题.利用约束方程进行分区网格划分,把一个模型分成多个形状规则的小区域并对其进行映像网格划分,然后使用约束方程,把相邻区域相接面上的单元节点联系起来.解决对复杂模型进行网格划分时很难划分出理想网格的问题,并对不同的小区域进行网格密度控制.
Abstract:
It has been a difficult issue to generate a mapped meshing for complicated models in finite elements, which are divided into many small quadrangles or small hexahedrons. Regional mapped meshing can be completed by constraint e-quation, in which a model is divided into several regular regions in shape. And then the constraint equation is used to link the nodes of different regions to deal with the difficult issue which ideal regions are hard to be obtained during the regional meshing of a complicated model, to implement the density regional control of small different regions.
