摘要
采用坐标变换方法，将物理平面中任意几何区域上的非均匀网格剖分映射到计算平面中规则区域上的均匀网格剖分。这种处理使得对某些问题的多重网格算法成为方便可行。文后给出了两个算例。
Abstract In this paper, an one to one maping is used to transfer an arbitrary domain and a nonuniform grid on it in physical plane to a rectangular domain with a uniform grid in computational plane. In this way, some kinds of partial differential equations can be solved conveniently on a uniform grid by using a rather standard multigrid methods. And two examples of numerical computation have been given here.
