Hybrid multigrid methods for high-order discontinuous Galerkin discretizations

Niklas Fehn, Peter Munch, Wolfgang A. Wall +1

The present work develops hybrid multigrid methods for high-order discontinuous Galerkin discretizations of elliptic problems. Fast matrix-free operator evaluation on tensor produc…
