基于实体变形的六面体网格生成方法研究

Automatic Hexahedral Mesh Generation with Geometry Transformation

对于结构复杂的实体模型,现有的六面体网格自动生成算法无法快速生成质量较高的六面体网格。在实体变形技术的基础之上,提出一种利用顶点信息直接在原始模型中经过节点填充生成结构化六面体网格的方法。首先设计了网格节点的数据结构;其次介绍了求解填充节点所用的线性方程组的构建方法;最后,利用该方法开发了网格自动剖分程序,对复杂结构进行了网格自动剖分。

General hexahedral mesh generation routines can not produce high-quality hexahedral grid efficiently for complex solid models. A structured hexahedral mesh generation approach based on model transforming is proposed, which is achieved directly in the original model by node-filling method using vertex information. The data structure of the grid node is designed firstly; then a construction method of linear equations for node-filling is introduced; at last, an auto-meshing program is developed successfully based on the approach.
