摘要: 研究了非结构网格的并行生成方法.改进了R.Lohner的"波阵面"区域分裂算法以使子网格及其边界更有益于网格并行生成,提出了边界并行优化策略,改善了边界的光滑性;完善了子区域内生成网格时接受新点及新单元的条件,在界面网格生成过程中提出只接受新单元而拒绝新点的策略,节省了机时.
关键词: 区域分裂算法, 非结构网格, 网格并行生成, 阵面推进法
Abstract: A parallel unstructured mesh generation method is studied. Lohner's advancing front domain-splitting algorithm is improved so that the subgrids and their boundaries are more favorable for grid generation. An optimization strategy of subdomain's boundary is presented to improve the smoothness of the boundaries and the quality of grids. The conditions for receiving new points and elements are developed in the course of grid generation in subdomains. And a new strategy which receives new elements and refuses new points during the interface grid generation is presented,which saves calculation time.
Key words: domain-splitting, unstructured grid, parallel grid generation, advancing front technique
