Graded Parametric CutFEM and CutIGA for Elliptic Boundary Value Problems in Domains with Corners

Tobias Jonsson, Mats G. Larson, Karl Larsson

We develop a parametric cut finite element method for elliptic boundary value problems with corner singularities where we have weighted control of higher order derivatives of the s…

Hybridized CutFEM for Elliptic Interface Problems

Erik Burman, Daniel Elfverson, Peter Hansbo +2

We design and analyze a hybridized cut finite element method for elliptic interface problems. In this method very general meshes can be coupled over internal unfitted interfaces, t…

A Stable Cut Finite Element Method for Partial Differential Equations on Surfaces: The Helmholtz-Beltrami Operator

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

We consider solving the surface Helmholtz equation on a smooth two dimensional surface embedded into a three dimensional space meshed with tetrahedra. The mesh does not respect the…

Cut Topology Optimization for Linear Elasticity with Coupling to Parametric Nondesign Domain Regions

Erik Burman, Daniel Elfverson, Peter Hansbo +2

We develop a density based topology optimization method for linear elasticity based on the cut finite element method. More precisely, the design domain is discretized using cut fin…

A Stabilized Cut Streamline Diffusion Finite Element Method for Convection-Diffusion Problems on Surfaces

Erik Burman, Peter Hansbo, Mats G. Larson +2

We develop a stabilized cut finite element method for the stationary convection diffusion problem on a surface embedded in . The cut finite element method is based…

A Cut Finite Element Method for Elliptic Bulk Problems with Embedded Surfaces

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

We propose an unfitted finite element method for flow in fractured porous media. The coupling across the fracture uses a Nitsche type mortaring, allowing for an accurate representa…
