A cut finite element method for the Biot system of poroelasticity
Nanna Berre, Kent-Andre Mardal, André Massing +1
We propose a novel cut finite element method for the numerical solution of the Biot system of poroelasticity. The Biot system couples elastic deformation of a porous solid with vis…

A better compression driver? CutFEM 3D shape optimization taking viscothermal losses into account
Martin Berggren, Anders Bernland, André Massing +2
The compression driver, the standard sound source for midrange acoustic horns, contains a cylindrical compression chamber connected to the horn throat through a system of channels…

Cut finite element discretizations of cell-by-cell EMI electrophysiology models
Nanna Berre, Marie E. Rognes, Andre Massing
The EMI (Extracellular-Membrane-Intracellular) model describes electrical activity in excitable tissue, where the extracellular and intracellular spaces and cellular membrane are e…
