HMG -- Homogeneous multigrid for HDG

Peipei Lu, Andreas Rupp, Guido Kanschat

We introduce a homogeneous multigrid method in the sense that it uses the same HDG discretization scheme for Poisson's equation on all levels. In particular, we construct a stable…

Fast Tensor Product Schwarz Smoothers for High-Order Discontinuous Galerkin Methods

Julius Witte, Daniel Arndt, Guido Kanschat

In this article, we discuss the efficient implementation of powerful domain decomposition smoothers for multigrid methods for high order discontinuous Galerkin (DG) finite element…

Multilevel Schwarz preconditioners for singularly perturbed symmetric reaction-diffusion systems

Jose Pablo Lucero Lorca, Guido Kanschat

We present robust and highly parallel multilevel non-overlapping Schwarz preconditioners, to solve an interior penalty discontinuous Galerkin finite element discretization of a sys…
