Abstract

Abstract:

An agglomeration multigrid algorithm has been developed to accelerate the convergence of the Euler equations to a steady state on unstructured meshes. In the present work, an efficient method has been designed to agglomerate unstructured meshes.The finite volume method is adopted on each layer.The high efficiency of this multigrid algorithm has been verified by calculating flows around a multielement airfoil.

Key words: unstructured mesh, agglomeration of meshes, multigrid, finite volume
