| Abstract: | A mapping of a free dimensional towel shaped region to a square transition region is constructed. A sufficient condition making the mapping be globally homeomorphic is obtained. The iterative method for the generation of the numerical grid depending on the mapping is given. For two especial cases of the towel shaped region, corrsponding results are presented. Finally, some examples are given showing the generation of numerical grid. |
