On the importance of smoothness, interface resolution and numerical sensitivities in shape and topological sensitivity analysis
M. H. Gfrerer, P. Gangl
In this paper we investigate the influence of the discretization of PDE constraints on shape and topological derivatives. To this end, we study a tracking-type functional and a two…

A computational model for short-range van der Waals interactions between beams and shells
Aleksandar BorkoviÄ, Michael H. Gfrerer, Roger A. Sauer
We consider potential-based interactions between beams (or fibers) and shells (or membranes) using a coarse-grained approach with focus on van der Waals attraction and steric repul…

Efficient snap-to-contact computations for van der Waals interacting fibers
Aleksandar BorkoviÄ, Michael H. Gfrerer, Roger A. Sauer +1
We consider van der Waals interactions between in-plane fibers, where the computational model employs the Lennard-Jones potential and the coarse-grained approach. The involved 6D i…
