First-order system least-squares finite element method for singularly perturbed Darcy equations
Thomas Führer, Juha Videman
We define and analyse a least-squares finite element method for a first-order reformulation of a scaled Brinkman model of fluid flow through porous media. We introduce a pseudostre…

Mortaring for linear elasticity using mixed and stabilized finite elements
Tom Gustafsson, Peter Råback, Juha Videman
The purpose of this work is to study mortar methods for linear elasticity using standard low order finite element spaces. Based on residual stabilization, we introduce a stabilized…
