[HTML][HTML] Geometric re-meshing strategies to simulate contactless rebounds of elastic solids in fluids

J Fara, S Schwarzacher, K Tůma - Computer Methods in Applied …, 2024 - Elsevier
The paper deals with the rebound of an elastic solid off a rigid wall of a container filled with
an incompressible Newtonian fluid. Our study focuses on a collision-free bounce, meaning a …

Adaptive time-step control for nonlinear fluid–structure interaction

L Failer, T Wick - Journal of Computational Physics, 2018 - Elsevier
In this work, we consider time step control for variational-monolithic fluid–structure
interaction. The fluid–structure interaction (FSI) system is based on the arbitrary Lagrangian …

Falling balls in a viscous fluid with contact: Comparing numerical simulations with experimental data

H von Wahl, T Richter, S Frei, T Hagemeier - Physics of Fluids, 2021 - pubs.aip.org
We evaluate a number of different finite-element approaches for fluid–structure (contact)
interaction problems against data from physical experiments. This consists of trajectories of …

On a fluid–structure interaction problem for plaque growth

H Abels, Y Liu - Nonlinearity, 2022 - iopscience.iop.org
We study a free-boundary fluid–structure interaction problem with growth, which arises from
the plaque formation in blood vessels. The fluid is described by the incompressible Navier …

An energy stable monolithic Eulerian fluid‐structure finite element method

F Hecht, O Pironneau - International Journal for Numerical …, 2017 - Wiley Online Library
When written in an Eulerian frame, the conservation laws of continuum mechanics are
similar for fluids and solids leading to a single set of variables for a monolithic formulation …
