Adaptive multigrid for high-order discontinuous Galerkin methods based on the full approximation scheme
Jörg Stiller
We propose an adaptive multigrid (MG) method for discontinuous Galerkin formulations of elliptic problems using Brandt's full approximation scheme (FAS). Unlike common approaches,…

Local high order space-time adaptive MLSDC
Erik Pfister, Matti Schulze, Jörg Stiller
Building upon the semi-implicit multilevel spectral deferred correction (SI-MLSDC) method introduced by Pfister and Stiller [38], this work presents a 1D space-time adaptive high-o…
