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…
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 New Least Squares Stabilized Nitsche Method for Cut Isogeometric Analysis
Daniel Elfverson, Mats G. Larson, Karl Larsson
We derive a new stabilized symmetric Nitsche method for enforcement of Dirichlet boundary conditions for elliptic problems of second order in cut isogeometric analysis (CutIGA). We…
CutIGA with Basis Function Removal
Daniel Elfverson, Mats G. Larson, Karl Larsson
We consider a cut isogeometric method, where the boundary of the domain is allowed to cut through the background mesh in an arbitrary fashion for a second order elliptic model prob…
Cut Finite Elements for Convection in Fractured Domains
Erik Burman, Peter Hansbo, Mats G. Larson +1
We develop a cut finite element method (CutFEM) for the convection problem in a so called fractured domain which is a union of manifolds of different dimensions such that a dim…
