| Abstract : | A Navier-Stokes multigrid method that has been developed for triangles and tetrahedra is extended to be used on hybrid grids. Various choices in extending the linear preserving flux calculation of the simplex scheme are discussed and a flexible way of expressing edge weights is presented. An edge-collapsing algorithm that generates the coarser levels of hybrid grids for a multigrid algorithm is described., |
