Unique continuation for the Lamé system using stabilized finite element methods

Erik Burman, Janosch Preuss

We introduce an arbitrary order, stabilized finite element method for solving a unique continuation problem subject to the time-harmonic elastic wave equation with variable coeffic…

Cut finite element method for divergence free approximation of incompressible flow: a Lagrange multiplier approach

Erik Burman, Peter Hansbo, Mats G. Larson

In this note we design a cut finite element method for a low order divergence free element applied to a boundary value problem subject to Stokes' equations. For the imposition of D…

Extension Operators for Trimmed Spline Spaces

Erik Burman, Peter Hansbo, Mats G. Larson +1

We develop a discrete extension operator for trimmed spline spaces consisting of piecewise polynomial functions of degree with continuous derivatives. The construction is b…

Continuous Interior Penalty stabilization for divergence-free finite element methods

Gabriel R. Barrenechea, Erik Burman, Ernesto Cáceres +1

In this paper we propose, analyze, and test numerically a pressure-robust stabilized finite element for a linearized problem in incompressible fluid mechanics, namely, the steady O…

Fully discrete loosely coupled Robin-Robin scheme for incompressible fluid-structure interaction: stability and error analysis

Erik Burman, Rebecca Durst, Miguel A. Fernández +1

We consider a fully discrete loosely coupled scheme for incompressible fluid-structure interaction based on the time semi-discrete splitting method introduced in {\emph{[Burman, Du…
