| 摘 要： | 给出了一种任意平面域内三角形网格自动生成的算法。本算法是根据下面两个事实而设计出来的：１．任意平面多连通域总可以剖分成若干个三角形单元。２．平面域内的活节点数目随着单元剖分总会趋近于零。文中还介绍了几种网格性能改善的方法。整个程序结构紧凑，需要人工输入的数据量少，生成的网格质量较高，而且算法稳定性能好。

| Abstract: | A efficient algorithm is presented for the automatic mesh generation of arbitrary planardomains into triangular elements,which is based on the facts,1.arbitray multiply connectedregions can always be divided into triangular elements,2.active nodes in this region tend tozero with the generation of triangular elements. Methods for improving the quality of ele-ments are given in this paper. The structure of this program has a well-knit plot with littleinput data,higher quality and stability. |
