Generalized eigenvalue stabilization for immersed explicit dynamics
Tim Bürchner, Lars Radtke, Sascha Eisenträger +4
Explicit time integration for immersed finite element discretizations severely suffers from the influence of poorly cut elements. In this contribution, we propose a generalized eig…
A CFL condition for the finite cell method
Tim Bürchner, Lars Radtke, Philipp Kopp
Immersed boundary finite element methods allow the user to bypass the potentially troublesome task of boundary-conforming mesh generation. When combined with explicit time integrat…
On the efficiency of explicit and semi-explicit immersed boundary finite element methods for wave propagation problems
Tim Bürchner, Lars Radtke, Philipp Kopp +3
Immersed boundary methods have attracted substantial interest in the last decades due to their potential for computations involving complex geometries. Often these cannot be effici…
Parameter-free shape optimization: various shape updates for engineering applications
Lars Radtke, Georgios Bletsos, Niklas Kühl +4
In the last decade, parameter-free approaches to shape optimization problems have matured to a state where they provide a versatile tool for complex engineering applications. Howev…
