【摘要】 基于推进波前法,本文提出了一种针对三维Trimmed参数曲面的有限元网格剖分方法。首先对曲面参数空间进行剖分,利用结点密度函数(与曲率有关)和生成内部结点的公式,使网格单元和结点能同时生成,然后把网格反映射到曲面上,从而实现参数曲面的三角形网格剖分。更多还原

【Abstract】 In this paper, an algorithm for partitioning a 3D Trimmed parametric surface into FEM mesh is presented. The algorithm is based on advancing front method with node density function controlled by the curvatures of both the boundary and the surface itself. Numerical results show that the mesh is much better than one obtained by other ways in qualities.更多还原
