摘要：

We describe a multigrid (MG) method for solving the Euler equations as applied to non-structured meshes in two (triangles) and three dimensions (tetrahedra). The main idea is to coarsen the given mesh by using topological neighboring relations. It is applied to upwind solvers relying on the MUSCL methodology. Two MG schemes are presented: an explicit Runge-Kutta FAS, and an implicit correction scheme. Transonic external flow computations are described for illustration.
