摘要: 将多重网格法运用于非结构网格.网格是通过聚合法得到的,网格之间是相互关联的.方程的求解采用Jamson的有限体积法.给出了二维、三维情况的数值算例.

关键词: 多重网格, 有限体积法, 非结构网格

Abstract: The multigrid method is applied in the unstructured grid. The coarse mesh is obtained by the "agglomerated" method. The Jamson's finite volume method is used for the calculation of the flow. Compared with the single mesh, the unstructured multigrid algorithm can accelerate the convergence and can improve the calculation efficiency, and the CPU time is largely reduced. The two-dimensional and three-dimensional numerical examples are presented.

Key words: multigrid method, finite volume method, unstructured grid
