摘要
用椭圆型方程生成网格。在二维发展两种Ｈｉｌｇｅｎｓｔｏｃｋ方法实现对网格与边界间距及与边界正交的控制，并将其思想推广到三维，生成了翼身尾组合体与公共交界面或边界面正交的三维贴体分块网格，用于Ｅｕｌｅｒ方程流场计算。
Two 2 d versions of Hilgenstock type source term correction method are developed for elliptic 2 d body fitted grid generation with orthogonality and spacing controlled on boundaries. A 3 d version of Hilgenstock type source term correction method is presented and used in block structured elliptic grid generation with orthogonality control on interfaces and boundaries. The Euler solution of flows around a wing body tail combination in generated grid predicts reasonable flow phenomena and wing surface pressure distribution in agreement with experiments.
