For the numerical treatment of elliptic boundary value problems, the coupling of boundary
element methods (BEM) and finite element methods (FEM) is widely used. Usually, the FEM …

The finite element method (FEM) and the boundary element method (BEM) can numerically
solve the Helmholtz system for acoustic wave propagation. When an object with …

We apply an expanded mixed finite element method, which introduces the gradient as a
third explicit unknown, to solve a linear second-order elliptic equation in divergence form …

We apply multiscale methods to the coupling of finite and boundary element methods to
solve an exterior two‐dimensional Laplacian. The matrices belonging to the boundary terms …

We analyze a multilevel diagonal additive Schwarz preconditioner for the adaptive coupling
of FEM and BEM for a linear 2D Laplace transmission problem. We rigorously prove that the …

We deal with the iterative solution of linear systems arising from so-called dual-dual mixed
finite element formulations. The linear systems are of a two-fold saddle point structure; they …

Several textbooks and monographs on preconditioners for FEM (finite element methods) are
available, but none exists for BEM (boundary element methods). For BEM, the topic is dealt …

Für nichtlineare Laplace-und Lamé-Transmissionsprobleme betrachten wir die
symmetrische als auch verschiedene Varianten der nicht-symmetrischen Kopplung von FEM …

The purpose of this paper is to present optimal preconditioned iterative methods to solve
indefinite linear systems of equations arising from symmetric coupling of finite elements and …

We investigate the minimum residual method for symmetric, indefinite linear systems of a so‐
called dual–dual structure. These systems arise when using a combined dual‐mixed finite …
