3D-2D Stokes-Darcy coupling for the modelling of seepage with an application to fluid-structure interaction with contact
Erik Burman, Miguel A. Fernández, Stefan Frei +1
In this note we introduce a mixed dimensional Stokes-Darcy coupling where a dimensional Stokes' flow is coupled to a Darcy model on the dimensional boundary of the domain…

Efficient approximation of flow problems with multiple scales in time
Stefan Frei, Thomas Richter
In this article we address flow problems that carry a multiscale character in time. In particular we consider the Navier-Stokes flow in a channel on a fast scale that influences th…

An adaptive Newton algorithm for optimal control problems with application to optimal electrode design
Thomas Carraro, Simon Dörsam, Stefan Frei +1
In this work we present an adaptive Newton-type method to solve nonlinear constrained optimization problems in which the constraint is a system of partial differential equations di…
