摘要
在三维非结构网格上应用聚合式多重网格技术来加速Euler方程的收敛过程.自行设计了一种高效率的网格聚合方法.采用四重三维非结构网格,在每一层网格上采用有限体积法进行计算.通过对M6翼型的数值求解验证了多重网格加速收敛的高效性.
An agglomeration multigrid algorithm has been developed to accelerate the convergence of the Euler equations to a steady state on three-dimensional unstructured meshes. In the present work, an efficient method has been designed to agglomerate three-dimensional unstructured meshes, by which we can generate coarse meshes good of quality. The finite volume method is adopted on each layer. The high efficiency of this multigrid algorithm has been verified by simulating flows around M6 airfoil.
