| 摘 要： | 本文提出一种快速生成二维贴体曲线网格的方法，即几何生成法．通过由区域边界简单代数插值得到预网格的节点坐标，建立起一一对应关系．然后根据网格疏密要求重新调整得到最终结果．与求解Ｐｏｉｓｓｏｎ方程得到坐标网格的ＴＴＭ法进行比较，用本法生成快速、布局较为合理，且能任意地调节疏密，这为流体力学中应用Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程进行数值计算提供了方便．

| Abstract: | A new method of grid generation in 2-D bodies, which is called Geometrically Grid Obtained Method(GGOM), is presented in this paper. It is quite convienient, simple and rapid to get the meshes used in 2-D body-fitted curvilinear ordinate system by some simple geometric operation in contrast to TTM method where complex numerical calculation of PDE is needed. The results show that the mesh configurations are suitable for engineering computation, and the calculations need much less CPU time than by TTM method. |
