摘要
提出一种二维结构网格的自适应生成方法,即采用变分方程控制网格的疏密程度以及光滑性、正交性和正规性,并且所有的控制方程具有一致的量纲.几个数值算例表明,给出的网格自适应生成方法能够较好地收敛到方程的唯一解,同时产生性质良好的二维自适应结构网格.
An adaptive generation method about two dimensional structured grids is presented.Several variational methods are used to control the mesh spacing,smoothness,orthogonality and regularity of grids generated.The all governing equations have identical dimensions.Some typical examples demonstrate that the method of adaptively generating grids can well converge to the unique solution of the governing partial differential equations, and in the meanwhile can get structured grids.
