应用多重网格法生成正交曲线网格

Application of multigrid method in the generation of orthogonal body- fitted curvilinear mesh

本文从势流理论出发,建立生成正交曲线网格的控制方程,应用多重网格法的FAS-FMG格式求解离散后的控制方程,不仅提高了收敛速度,而且提高了正交曲线网格的生成质量。

In this paper, the governing equations of orthogonal body -fitted curvilinear mesh is derived based on the theory of potential flow. A procedure to solve the governing equations using multigrid method is introduced. FAS -FMG scheme is tested, the method proposed is rapid and stable. The satisfactory results have been obtained.
