Finite-Dimensional MOR-Based RHC for Steering 2D Navier-Stokes Equations to Desired Trajectories
Behzad Azmi, Stefan Frei, Felix Sauer
This paper investigates the local exponential stabilization of the two-dimensional Navier--Stokes equations to a given reference trajectory by means of receding horizon control (RH…
Numerical Analysis of a Cut Finite Element Approach for Fully Eulerian Fluid-Structure Interaction with Fixed Interface
Stefan Frei, Tobias Knoke, Marc C. Steinbach +2
This work develops and analyzes a variational-monolithic unfitted finite element formulation of a linear fluid-structure interaction problem in Eulerian coordinates with a fixed in…
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…
A non-intrusive neural-network based BFGS algorithm for parameter estimation in non-stationary elasticity
Stefan Frei, Jan Reichle, Stefan Volkwein
We present a non-intrusive gradient and a non-intrusive BFGS algorithm for parameter estimation problems in non-stationary elasticity. To avoid multiple (and potentially expensive)…
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…
