Parallel matrix-free higher-order finite element solvers for phase-field fracture problems
Daniel Jodlbauer, Ulrich Langer, Thomas Wick
Phase-field fracture models lead to variational problems that can be written as a coupled variational equality and inequality system. Numerically, such problems can be treated with…
Reliability and efficiency of DWR-type a posteriori error estimates with smart sensitivity weight recovering
Bernhard Endtmayer, Ulrich Langer, Thomas Wick
We derive efficient and reliable goal-oriented error estimations, and devise adaptive mesh procedures for the finite element method that are based on the localization of a posterio…
A global-local approach for hydraulic phase-field fracture in poroelastic media
Fadi Aldakheel, Nima Noii, Thomas Wick +1
In this work, phase-field modeling of hydraulic fractures in porous media is extended towards a global-local approach. Therein, the failure behavior is solely analyzed in a (small)…
Dynamic and weighted stabilizations of the -scheme applied to a phase-field model for fracture propagation
Christian Engwer, Iuliu Sorin Pop, Thomas Wick
We consider a phase-field fracture propagation model, which consists of two (nonlinear) coupled partial differential equations. The first equation describes the displacement evolut…
Hierarchical DWR Error Estimates for the Navier Stokes Equation: and Enrichment
B. Endtmayer, U. Langer, J. P. Thiele +1
In this work, we further develop multigoal-oriented a posteriori error estimation for the nonlinear, stationary, incompressible Navier-Stokes equations. It is an extension of our p…
Optimization with nonstationary, nonlinear monolithic fluid-structure interaction
Thomas Wick, Winnifried Wollner
Within this work, we consider optimization settings for nonlinear, nonstationary fluid-structure interaction. The problem is formulated in a monolithic fashion using the arbitrary…
