Multi-staging of Jacobi relaxation in multigrid methods for steady Euler equations. 2.
AbstractMulti-stage versions of Jacobi relaxation are studied for use in multigrid methods for steady Euler equations. In particular, versions adapted to the nonlinear TVD discretization are analysed. It is shown that multi-stage relaxation versions lead to more efficient multigrid methods than possible with classic relaxation methods
A multigrid method with unstructured adaptive grids for steady Euler equations.
AbstractThe multigrid method based on multi-stage Jacobi relaxation, earlier developed by the authors for structured grid calculations with Euler equations, is extended to unstructured grid applications. The meshes are generated with Delaunay triangulation algorithms and are adapted to the flow solution
Multi-staging of Jacobi relaxation to improve smoothing properties of multigrid methods for steady Euler equations.
AbstractMulti-stage versions of Jacobi relaxation are studied for use in multigrid methods for steady Euler equations. It is shown that these multi-stage versions allow much more general and much more efficient multigrid methods than possible with classic relaxation methods
