On the implementation of an adaptive multirate framework for coupled transport and flow

Marius Paul Bruchhäuser, Uwe Köcher, Markus Bause

In this work, a multirate in time approach resolving the different time scales of a convection-dominated transport and coupled fluid flow is developed and studied in view of goal-o…

A mixed discontinuous-continuous Galerkin time discretisation for Biot's system

Uwe Köcher, Markus Bause

We study higher-order space-time variational discretisations for modeling complex processes in porous media that include fluid and structure interactions which are of fundamental i…

Post-processed Galerkin approximation of improved order for wave equations

Markus Bause, Uwe Köcher, Florin A. Radu +1

We introduce and analyze a post-processing for a family of variational space-time approximations to wave problems. The discretization in space and time is based on continuous finit…

Numerical investigation on the fixed-stress splitting scheme for Biot's equations: Optimality of the tuning parameter

Jakub Wiktor Both, Uwe Köcher

We study the numerical solution of the quasi-static linear Biot's equations solved iteratively by the fixed-stress splitting scheme. In each iteration the mechanical and flow probl…

Influence of the SIPG penalisation on the numerical properties of linear systems for elastic wave propagation

Uwe Köcher

Interior penalty discontinuous Galerkin discretisations (IPDG) and especially the symmetric variant (SIPG) for time-domain wave propagation problems are broadly accepted and widely…

Error analysis for discretizations of parabolic problems using continuous finite elements in time and mixed finite elements in space

Markus Bause, Florin A. Radu, Uwe Köcher

Variational time discretization schemes are getting of increasing importance for the accurate numerical approximation of transient phenomena. The applicability and value of mixed f…
