Finite Element Methods for One Dimensional Elliptic Distributed Optimal Control Problems with Pointwise Constraints on the Derivative of the State
Susanne C. Brenner, Li-Yeng Sung, Winnifried Wollner
We investigate finite element methods for one dimensional elliptic distributed optimal control problems with pointwise constraints on the derivative of the state formulated a…

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…

Mesh adaptivity for quasi-static phase-field fractures based on a residual-type a posteriori error estimator
Katrin Mang, Mirjam Walloth, Thomas Wick +1
In this work, we consider adaptive mesh refinement for a monolithic phase-field description for fractures in brittle materials. Our approach is based on an a posteriori error estim…
