Two-side a posteriori error estimates for the DWR method
Bernhard Endtmayer, Ulrich Langer, Thomas Wick
In this work, we derive two-sided a posteriori error estimates for the dual-weighted residual (DWR) method. We consider both single and multiple goal functionals. Using a saturatio…
Parallel solution, adaptivity, computational convergence, and open-source code of 2d and 3d pressurized phase-field fracture problems
Timo Heister, Thomas Wick
We present a scalable, parallel implementation of a solver for the solution of a phase-field model for quasi-static brittle fracture. The code is available as open source. Numerica…
On the implementation of a locally modified finite element method for interface problems in deal.II
Stefan Frei, Thomas Richter, Thomas Wick
In this work, we describe a simple finite element approach that is able to resolve weak discontinuities in interface problems accurately. The approach is based on a fixed patch mes…
Multigoal-Oriented Error Estimates for Non-linear Problems
B. Endtmayer, U. Langer, T. Wick
In this work, we further develop multigoal-oriented a posteriori error estimation with two objectives in mind. First, we formulate goal-oriented mesh adaptivity for multiple functi…
Parallel Block-Preconditioned Monolithic Solvers for Fluid-Structure-Interaction Problems
D. Jodlbauer, U. Langer, T. Wick
In this work, we consider the solution of fluid-structure interaction problems using a monolithic approach for the coupling between fluid and solid subproblems. The coupling of bot…
