Subsweep: Extensions to the Sweep method for radiative transfer
Toni Peter, Joseph S. W. Lewis, Ralf S. Klessen +2
We introduce the radiative transfer postprocessing code Subsweep. The code is based on the method of transport sweeps, in which the exact solution to the scattering-less radiative…

Monolithic two-level Schwarz preconditioner for Biot's consolidation model in two space dimensions
Stefan Meggendorfer, Guido Kanschat, Johannes Kraus
This paper addresses the construction and analysis of a class of domain decomposition methods for the iterative solution of the quasi-static Biot problem in three-field formulation…

Homogeneous multigrid method for HDG applied to the Stokes equation
Peipei Lu, Wei Wang, Guido Kanschat +1
We propose a multigrid method to solve the linear system of equations arising from a hybrid discontinuous Galerkin (in particular, a single face hybridizable, a hybrid Raviart--Tho…
