摘　　要：提出了为用Delaunay法自动生成无结构网格而发展的“墨浸式”加点法。采用“墨浸式”加入边界点的方法 ,使得Delaunay方法的固有缺陷 ,即可能出现边界穿透的问题 ,得到简化。“墨浸式”加点法成功地在一些复杂边界域内生成了可用于流场计算的无结构网格。It develops and describes a new method, the ink soak method, for adding boundary points in generation of three dimensional unstructured meshes with Delaunay method. In the Delaunay method, there is an essential defect, i.e., the generated meshes can cross with bound of domain and do not coincide with it, specially in 3D problems. To overcome this difficulty, some complicated methods to check and to correct them were designed. All these method need numerous computational time. This problem is greatly simplified by the present ink soak method. Some 3 D examples are given and demonstrate the efficiency of the ink soak method for unstructured grid generation in complex regions. [
