| Abstract: | 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. |
