The numerical analysis of electromagnetic devices by means of finite element methods (FEM) is often hindered by the need to incorporate the surrounding domain. The discretisation of the air may become complex and has to be truncated by artificial bou

We present a fixed-grid finite element technique for fluid-structure interaction problems involving incompressible viscous flows and thin structures. The flow equations are discretised with isoparametric b-spline basis functions defined on a logicall

We present an immersed finite element technique for boundary-value and interface problems from nonlinear solid mechanics. Its key features are the implicit representation of domain boundaries and interfaces, the use of Nitsche’s method for the inco

Electrical machines commonly consist of moving and stationary parts. The field simulation of such devices can be very demanding if the underlying numerical scheme is solely based on a domain discretization, such as in case of the Finite Element Metho

An immersed finite element method for solid–fluid interaction is presented with application focus on highly deformable elastic bodies in a Stokes flow environment. The method is based on a global balance equation which combines the solid and fluid

SUMMARY We propose a robust immersed finite element method in which an integral equation formulation is used to enforce essential boundary conditions. The solution of a boundary value problem is expressed as the superposition of a finite element solu

A collocation boundary element formulation is presented which is based on a mixed approximation for- mulation similar to the Galerkin boundary element method presented by Steinbach (SIAM J Numer Anal 38:401-413, 2000) for the solution of Laplace's eq

A coupling algorithm is presented, which allows for the flexible use of finite and boundary element methods as local discretization methods. On the subdomain level, Dirichlet-to-Neumann maps are realized by means of each discretization method. Such m
