A locally modified second-order finite element method for interface problems

  title={A locally modified second-order finite element method for interface problems},
  author={Stefan Frei and Gozel Judakova and Thomas Richter},
The locally modified finite element method, which is introduced in [Frei, Richter: SINUM 52(2014), p. 2315-2334] is a simple fitted finite element method that is able to resolve weak discontinuities in interface problems. The method is based on a fixed structured coarse mesh, which is then refined into sub-elements to resolve an interior interface. In this work, we extend the locally modified finite element method to second order using an isoparametric approach in the interface elements… 

An implicitly extended Crank-Nicolson scheme for the heat equation on time-dependent domains

We consider a time-stepping scheme of Crank-Nicolson type for the heat equation on a moving domain in Eulerian coordinates. As the spatial domain varies between subsequent time steps, an extension of



A sharp interface method using enriched finite elements for elliptic interface problems

An immersed boundary method for the solution of elliptic interface problems with discontinuous coefficients which provides a second-order approximation of the solution and the stability and convergence will be proven and the numerical tests demonstrate optimal order of convergence.

A Locally Modified Parametric Finite Element Method for Interface Problems

A modified finite element method that is able to approximate interface problems with high accuracy is presented, and optimal order of convergence for elliptic problems is shown and a bound on the condition number of the system matrix is given.

In this paper, we analyze a stabilized equal‐order finite element approximation for the Stokes equations on anisotropic meshes. In particular, we allow arbitrary anisotropies in a subdomain, for

Eulerian finite element methods for interface problems and fluid-structure interactions

An accurate and robust numerical framework for interface problems involving moving interfaces based on the monolithic "Fully Eulerian" approach for fluid-structure interactions (FSI) is developed and validated with the help of established numerical benchmarks.

A finite element method for interface problems in domains with smooth boundaries and interfaces

It is shown that the error in the finite element approximation is of optimal order for linear elements on a quasiuniform triangulation.

The proposed approach on a model problem — the Dirichlet problem with an interface for Laplace equation with sufficient condition for the smoothnees can be determined, and the boundary of the domain and the interface will be assumed smooth enough.

Fictitious domain finite element methods using cut elements

A finite element method for crack growth without remeshing

SUMMARY An improvement of a new technique for modelling cracks in the nite element framework is presented. A standard displacement-based approximation is enriched near a crack by incorporating both

Numerical simulation of parabolic moving and growing interface problems using small mesh deformation

This new method is able to resolve large displacement or deformation of immersed objects by combining the Arbitrary Lagrangian-Eulerian method with only small local mesh deformation defined on the reference domain, that is decomposed into the macro-elements.
