摘要
给出了一种把任意维方形过渡域自适应映到最终计算域的映射;给出了此映射是全局同胚的充分性条件,以及对应此映射的数值网格生成迭代方法.用全局同胚自适应网格生成的例子进一步表明本文方法是实际可行的.
In this paper,a mapping of a free dimensional square transition region to a square computational region is given.A sufficient condition making the mapping global homeomorphic is obtained.The iterative method for the generation of numerical grids depending on the mapping is presented.Finally,the present method is proved to be feasible with examples of generation of numerical grids.
