摘要
本文对贴体坐标数值求解拉普拉斯方程作一总体介绍,讨论了不同网格类型下在计算平面中如何正确地实现物理边界条件并克服网格类型所带来的不利影响,对于复杂的流动问题建议采用分块网格系统和增加连接网格的方法来提高网格的光滑性。
The general description has been made for numerical solving Laplace equation with body fitted grid. It is discussed how to apply correctly physical boundary condition to computational plane with different grid type and overcome shortcoming from different grid type. It is suggestion that multi-segmented (block) grid generation and increasing connect segmented grid should be done for complex fluid flow in order to improve the smoothness of grid.
