An unfitted hybrid high-order method for elliptic interface problems

E Burman, A Ern - SIAM Journal on Numerical Analysis, 2018 - SIAM
We design and analyze a hybrid high-order (HHO) method on unfitted meshes to
approximate elliptic interface problems. The curved interface can cut through the mesh cells …

A Nitsche-based formulation for fluid-structure interactions with contact

E Burman, MA Fernández, S Frei - ESAIM: Mathematical Modelling …, 2020 - esaim-m2an.org
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 J. Numer. Anal. 51 …

Virtual element methods for general linear elliptic interface problems on polygonal meshes with small edges
