摘要
构造一种新的源项修正方法用于三维椭圆型方程网格生成,可以实现对网格与边界正交及网格与边界间距的双重直接控制.
A new source term correction method is presented for 3 d elliptic grid generation. The grid generated by the new method can be made orthogonal to one specified family of boundaries and the spacings of the first layer grid points off the boundaries can be controlled to equal an expected distribution. A C O type grid for a delta wing is generated as an example.
