Tensor-product space-time goal-oriented error control and adaptivity with partition-of-unity dual-weighted residuals for nonstationary flow problems
Julian Roth, Jan Philipp Thiele, Uwe Köcher +1
In this work, the dual-weighted residual method is applied to a space-time formulation of nonstationary Stokes and Navier-Stokes flow. Tensor-product space-time finite elements are…
Matrix-free Monolithic Multigrid Methods for Stokes and Generalized Stokes Problems
Daniel Jodlbauer, Ulrich Langer, Thomas Wick +1
We consider the widely used continuous - quadrilateral or hexahedral Taylor-Hood elements for the finite element discretization of the Stokes an…
Robust preconditioning for a mixed formulation of phase-field fracture problems
Timo Heister, Katrin Mang, Thomas Wick
In this work, we consider fracture propagation in nearly incompressible and (fully) incompressible materials using a phase-field formulation. We use a mixed form of the elasticity…
Parallel domain decomposition solvers for the time harmonic Maxwell equations
Sven Beuchler, Sebastian Kinnewig, Thomas Wick
The time harmonic Maxwell equations are of current interest in computational science and applied mathematics with many applications in modern physics. In this work, we present para…
Adjoint-based methods for optimization and goal-oriented error control applied to fluid-structure interaction: implementation of a partition-of-unity dual-weighted residual estimator for stationary forward FSI problems in deal.II
Thomas Wick
In this work, we implement goal-oriented error control and spatial mesh adaptivity for stationary fluid-structure interaction. The a posteriori error estimator is realized using th…
A mixed phase-field fracture model for crack propagation in punctured EPDM strips
Katrin Mang, Andreas Fehse, Nils Hendrik Kröger +1
In this work, we present crack propagation experiments evaluated by digital image correlation (DIC) for a carbon black filled ethylene propylene diene monomer rubber (EPDM) and num…
