The Johnson-Nédélec FEM-BEM Coupling for magnetostatic problems in the isogeometric framework
Mehdi Elasmi, Christoph Erath, Stefan Kurz
We consider a Johnson-Nédélec FEM-BEM coupling, which is a direct and non-symmetric coupling of finite and boundary element methods, in order to solve interface problems for the ma…
Mortar coupling of -discontinuous Galerkin and boundary element methods for the Helmholtz equation
Christoph Erath, Lorenzo Mascotto, Jens Markus Melenk +2
We design and analyze a coupling of a discontinuous Galerkin finite element method with a boundary element method to solve the Helmholtz equation with variable coefficients in thre…
Non-symmetric isogeometric FEM-BEM couplings
Mehdi Elasmi, Christoph Erath, Stefan Kurz
We present a coupling of the Finite Element and the Boundary Element Method in an isogeometric framework to approximate either two-dimensional Laplace interface problems or boundar…
Optimal Adaptivity for the SUPG Finite Element Method
Christoph Erath, Dirk Praetorius
For convection dominated problems, the streamline upwind Petrov--Galerkin method (SUPG), also named streamline diffusion finite element method (SDFEM), ensures a stable finite elem…
Stable non-symmetric coupling of the finite volume and the boundary element method for convection-dominated parabolic-elliptic interface problems
Christoph Erath, Robert Schorr
Many problems in electrical engineering or fluid mechanics can be modeled by parabolic-elliptic interface problems, where the domain for the exterior elliptic problem might be unbo…
Optimal convergence behavior of adaptive FEM driven by simple (h-h/2)-type error estimators
Christoph Erath, Gregor Gantner, Dirk Praetorius
For some Poisson-type model problem, we prove that adaptive FEM driven by the (h-h/2)-type error estimators from [Ferraz-Leite, Ortner, Praetorius, Numer. Math. 116 (2010)] leads t…
