Abstract

This paper deals with the coupling of finite elements and boundary elements for the calculation of 3D magnetic fields in media with hysteresis. For the description of hysteresis effects the vector Preisach model is used. The numerical implementation of the 3D vector Preisach model is addressed. A boundary value problem (bvp) with ferromagnetic material for which an analytical solution exists is presented. This bvp can be used to validate the numerical approach. Numerical and analytical solution of the bvp show very good agreement
