A new shape optimization approach for fracture propagation
Tim Suchan, Kathrin Welker, Winnifried Wollner
Within this work, we present a novel approach to fracture simulations based on shape optimization techniques. Contrary to widely-used phase-field approaches in literature the propo…
Pressure robust mixed methods for nearly incompressible elasticity
Seshadri R. Basava, Winnifried Wollner
Within the last years pressure robust methods for the discretization of incompressible fluids have been developed. These methods allow the use of standard finite elements for the s…
A Successive Linear Relaxation Method for MINLPs with Multivariate Lipschitz Continuous Nonlinearities
Julia Grübel, Richard Krug, Martin Schmidt +1
We present a novel method for mixed-integer optimization problems with multivariate and Lipschitz continuous nonlinearities. In particular, we do not assume that the nonlinear cons…
Pressure-robustness in the context of optimal control
Christian Merdon, Winnifried Wollner
This paper studies the benefits of pressure-robust discretizations in the scope of optimal control of incompressible flows. Gradient forces that may appear in the data can have a n…
