利用点源或线源所影响的势函数分布规律，通过建立势函数与网格背景信息之间的关系，提供非结构网格生成过程中所需的网格背景参数;在物体边界节点已知的情况下，适当布置点源和线源个数，用最小二乘法确定各点源和线源的强度;通过对部分点源或线源的影响势函数施加方向控制开关，使所生成的网格在期望的区域得到加密;算例表明本文方法是一种有效、快速的处理方法，与传统用背景网格提供背景信息的方法相比，在计算量、程序量、光滑性和灵活性方面都能表现出良好的性质。
By using the distribution of potential functions affected by point sources or line sources, the grid background parameters needed in the generation of unstructured grids are provided by establishing the relationship between potential functions and grid background information. When the boundary nodes of objects are known , The number of point sources and line sources are properly arranged, and the intensity of each point source and line source is determined by the least square method. By applying the direction control switch to the influence potential function of some point sources or line sources, the generated network The results show that the proposed method is an efficient and rapid processing method. Compared with the traditional method of background information provided by the background grid, the computational complexity, program quality, smoothness and flexibility Can show good character.
