| 摘 要： | 根据Delaunay原理给出了一种具有特征约束的有限单元的三角网格的核心思想、生成方法、算法过程。该智能化方法的核心是同时考虑计算机的自动化和人的经验的共同作用的需要，同时综合考虑了三种内部约束条件：固定结点、固定边、孤岛，在此基础上灵活的设置剖分尺寸进行边界的离散化，然后开始外边界的扩展、插入离散的点后自动地生成了初始的网格。最终利用良好的人机交互界面进行校正。生成真正满足计算需求和实际情况的三角网格。

| Abstract: | The mind and algorithm realizing finite element meshing according the Delaunay dividing principle is given, which is explicit and clear. This intelligent method meets the need of auto-generator and personal involved at the same time, and some special inner restriction is considered during the course of automatic mesh generator. Three types of inner restrictions including fixed node a, fixed element boundary and isolated area. The boundaries can be scattered according to the need of dividing size, and then expand the outer boundary, insert discrete nodes, thus generate the initial mesh. At last the need mesh can be revised by using the man-machine conversation windows. |
