An edge-based pressure stabilisation technique for finite elements on arbitrarily anisotropic meshes
Stefan Frei
In this article, we analyse a stabilised equal-order finite element approximation for the Stokes equations on anisotropic meshes. In particular, we allow arbitrary anisotropies in…
A Nitsche-based formulation for fluid-structure interactions with contact
Erik Burman, Miguel A. Fernández, Stefan Frei
We derive a Nitsche-based formulation for fluid-structure interaction (FSI) problems with contact. The approach is based on the work of Chouly and Hild [SIAM Journal on Numerical A…
On the implementation of a locally modified finite element method for interface problems in deal.II
Stefan Frei, Thomas Richter, Thomas Wick
In this work, we describe a simple finite element approach that is able to resolve weak discontinuities in interface problems accurately. The approach is based on a fixed patch mes…
Finite element simulation of fluid dynamics and CO gas exchange in the alveolar sacs of the human lung
Luis J. Caucha, Stefan Frei, Obidio Rubio
In this article we present a numerical framework based on continuum models for the fluid dynamics and the CO gas distribution in the alveolar sacs of the human lung during expi…
