一种简单快速的多块网格生成方法

A New Multi-Block Mesh Generation Method

利用有限元中的形函数进行网格插值映射分块生成网格 ,构造了一种块网格拓扑结构 ,使得块与相邻块之间自动组合 ,并利用该方法对二维、三维复杂区域进行分块网格生成 ,说明该方法生成的网格质量较好 。

In this paper, a multi block, body fitted mesh generation method is presented, which takes advantage of shape function in finite element to carry on interpolation and mapping for each block mesh generation. A block mesh topology is also developed, which can make a block to merge its neighbouring ones. It proves that the mesh generated by this method is such a good quality. The present method can be fitted for solving complex geometry flows.
