基于片分割的六面体网格生成方法

Hexahedral Mesh Generation Method Based on Sheet-Division

为了发展一种保证边界质量、考虑全局信息、具有较高计算效率的六面体网格生成技术,提出了基于片分割的六面体网格生成方法.首先在标架场的指引下由实体表面的环扩展出一层六面体单元,然后用该六面体单元层将原实体分割为2个更小规模的子实体,最后采用同样的方式递归处理子实体直至子实体为空.该方法采用分而治之的策略,适宜于并行化.数值实验结果表明,文中方法生成的网格与当前领先的网格生成方法生成的网格质量相当.

For the purpose of developing a hexahedral mesh generation technique which ensures the boundaryquality,considers global information and has the potential to speed highly,we presented a hexahedral mesh generationmethod based on sheet-division.First,we extended the loop of the surface of a solid to a layer of hexahedralelements,and then divided the solid into two smaller sub-solids by the layer,finally dealt with them recursivelyuntil all the sub-solids are empty.A strategy of divide-and-conquer used in this method is suitable for parallelization.The testing results show that the quality of the meshes generated by this method is similar with thoseproduced by the current state-of-art mesh generation methods.
