| 摘 要： | 利用ＰＥＤＳ（ＰａｒａｍｅｔｒｉｃＥｎｇｉｎｅｅｒｉｎｇＤｅｓｉｇｎＳｙｓｅｍ）造型系统的几何，拓扑信息实现了二维有限元网格自动生成，在实现过程中，改进了Ｗａｓｔｏｎ三角化算法，把此方法应用到有限元剖分中，还利用了迭代的Ｌａｐｌａｃｉａｎ算法对网格进行了均匀化处理，另外，还提供了可靠，快速对网格编辑，局部细化的方法，最终使有限元网格生成完全自动化，而且速度快，质量好，密度易于控制。

| Abstract: | D mesh generation automatically utilizing geometry and topology information in PEDSmodelling system is realized. In the process,we apply Waston's triangularization algorithm in finite element mesh generation through improving it,and use iterative Laplacian algorithm to smooth mesh. In addition,this article supplies reliable and prompt methods to edit and refine mesh. Finally,we generate mesh fully automatically, promptly and in high-quality,and control mesh density easily. |
