摘要: A multigrid algorithm has been developed to accelerate the convergence of Euler equations a steady state on unstructured triangular meshes. The method operates sequence coarse and fine meshes assumes no relation exists between various tree-search is used efficiently identify regions overlap grid cells. applied two different discretizations equations, results about multi-element airfoils are presented. For both discretization schemes, accelerated by an order magnitude, resulting in rates comparable those obtained with structured algorithms.
