Analysis of optimal preconditioners for CutFEM
Sven Gross, Arnold Reusken
In this paper we consider a class of unfitted finite element methods for scalar elliptic problems. These so-called CutFEM methods use standard finite element spaces on a fixed unfi…
Optimal preconditioners for a Nitsche stabilized fictitious domain finite element method
Sven Gross, Arnold Reusken
In this paper we consider a class of fictitious domain finite element methods known from the literature. These methods use standard finite element spaces on a fixed unfitted triang…
A Multigrid Method for Unfitted Finite Element Discretizations of Elliptic Interface Problems
Thomas Ludescher, Sven Gross, Arnold Reusken
We consider discrete Poisson interface problems resulting from linear unfitted finite elements, also called cut finite elements (CutFEM). Three of these unfitted finite element met…
A Trace Finite Element Method for Vector-Laplacians on Surfaces
Sven Groß, Thomas Jankuhn, Maxim A. Olshanskii +1
We consider a vector-Laplace problem posed on a 2D surface embedded in a 3D domain, which results from the modeling of surface fluids based on exterior Cartesian differential opera…
Memory-efficient recycling of large Krylov-subspaces for sequences of Hermitian linear systems
Martin Peter Neuenhofen, Sven Groß
We present a new short-recurrence reaidual-optimal Krylov subspace recycling method for sequences of Hermitian systems of linear equations with a fixed system matrix and changing r…
A trace finite element method for a class of coupled bulk-interface transport problems
Sven Gross, Maxim A. Olshanskii, Arnold Reusken
In this paper we study a system of advection-diffusion equations in a bulk domain coupled to an advection-diffusion equation on an embedded surface. Such systems of coupled partial…
