【摘要】 采用求解抛物化的椭圆型方程和物面网格自适应方法生成三维复杂外形网格 ,保留了椭圆型方程解析性好的特点 ,同时又可以推进求解 ,不须迭代 .所生成的网格贴体性、光滑性、均匀性、物面及空间正交性等方面可以满足复杂流动计算
【Abstract】 In this paper, 3 D grids for complicated shapes are generated by solving parabolic partial differential equations and adaptive surface grid distribution. The method have the good feature of elliptic trid and can be solved by marching technology which needn’t iteration. The grids generated by solving parabolic partial differential equations have advantage in smooth、uniformity、body conforming and orthogonality at surface and space. It can be used in complicated flow calculation.
