Numerical Simulations of Fully Eulerian Fluid-Structure Contact Interaction using a Ghost-Penalty Cut Finite Element Approach
Stefan Frei, Tobias Knoke, Marc C. Steinbach +2
In this work, we develop a cut-based unfitted finite element formulation for solving nonlinear, nonstationary fluid-structure interaction with contact in Eulerian coordinates. In t…

Modeling and numerical simulation of fully Eulerian fluid-structure interaction using cut finite elements
Stefan Frei, Tobias Knoke, Marc C. Steinbach +2
We present a monolithic finite element formulation for (nonlinear) fluid-structure interaction in Eulerian coordinates. For the discretization we employ an unfitted finite element…

Efficient coarse correction for parallel time-stepping in plaque growth simulations
Stefan Frei, Alexander Heinlein
In order to make the numerical simulation of atherosclerotic plaque growth feasible, a temporal homogenization approach is employed. The resulting macro-scale problem for the plaqu…
