Abstract: This paper summarizes the development of search in mesh generation for finite element computation in last ten years. Firstly, the principle of meshing is researched. Secondly, the main research fields, such as mapping methods, grid-based approach, point distribution and triangulation approach, topology decomposition approach, geometry decomposition approach, sweeping approach, are discussed and classified. Uniting instances, it analyses systematically the principle, characteristics and scopes of these methods. Thirdly, the front edge is narrated and hexahedral mesh is reviewed. Finally, this paper prospects the trend FEM.

Key words: finite element mesh generation, mapping approach, grid-based approach, point distribution and triangulation approach, topology decomposition approach, geometry decomposition approach, sweeping approach, hexahedral mesh

摘要: 总结近十年有限元网格划分技术发展状况。首先,研究和分析有限元网格划分的基本原则;其次,对当前典型网格划分方法进行科学地分类,结合实例,系统地分析各种网格划分方法的机理、特点及其适用范围,如映射法、基于栅格法、节点连元法、拓扑分解法、几何分解法和扫描法等;再次,阐述当前网格划分的研究热点,综述六面体网格和曲面网格划分技术;最后,展望有限元网格划分的发展趋势。
