摘要
本文对空间板壳结构的有限元网格自动生成进行了研究,讨论了结构整体网格的拼合及可展曲面的网格自动生成等问题,并提出了一个新的二维三角形网格自动生成算法,算法具有精确拟合边界、多连通域处理及局部网格加密等功能.
The automatic FEM mesh generation for a spatial Plate-shell structure is studied. Piecing together of the entire mesh of the structure and the automatic mesh generation of a developable surface are discussed. A new 2-D triangular mesh generation algorithm with some powerful functions including accurate boundary fitting, multi-connected region handling and local mesh densification is developed.
