| 摘 要： | 提出了一种基于STL数据的有限元网格再生成算法,该算法主要用于CAE工程分析.鉴于CAD模型的网格特征形态不匀称,分布不均匀的特点,对CAD模型进行网格再生成,使其符合CAE工程分析的要求.算法主要由拓扑建立、网格聚类、网格重采样和三角化四部分组成.实验表明该算法能够有效降低三角网格最长边和最短边的比值,使得模型的网格特征形态趋于均匀.

| Abstract: | The paper presents an algorithm of the Finite Element mesh generation based on STL Data. The algorithm is mainly used for CAE engineering analysis. Considering the bad shape of STL model from CAD system, we need re-meshing the STL model so that the shape of triangular is better use for CAE analysis. The algorithm includes 4 steps： topologic creation, mesh clustering, mesh re-sampling, triangulation. The results show that our algorithm can reduce the ratio of the longest edge and the shortest edge of triangle mesh effectively to make shape of triangular is in uniform. |
