A review of FEM and trend of development

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.
