摘要
本文描述了非结构网格生成的过程。在生成方法上综合Ｄｅｌａｕｎｅｙ和ＡｄｖａｎｃｉｎｇＦｒｏｎｔ两种方法之长，构造了新的网格生成方法，使非结构网格生成更方便、快捷。网格生成过程分三个部分：１．表面网格的构造和最佳逼近；２．辅助点的生成与确定；３．空间四面体网格的生成。使用上述方法。
In this article, an unstructured grid generation process is described. A new unstructured grid generation method is composed by combining the Delauney Method and the Adyancing Fronter Method. This method made 3-D unstructured grid generation faster and more convenient.The process of grid generation includes three parts: 1. surface grid generation; 2. auxiliary points generation; 3. 3-D unstructured grid generation. Using this method, we generated some complicated configuration's unstructured grid successfully.
