Unstructured multigridding by volume agglomeration : current status

Abstract : We describe a multigrid method for solving the Euler equations applying to non-structured meshes in 2-D (triangles) and 3-D (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 multigrid schemes are presented : an explicit Runge-Kutta FAS one and an implicit correction scheme. Transonic external flows computations are described for illustration.
