The Newton-Raphson method for solving non-linear and anisotropic time-harmonic problems
This paper discusses the use of a complex-valued reluctivity tensor for modelling non-linear, anisotropic and hysteretic materials in a time-harmonic finite element context. It is shown how these problems can be solved by the Newton-Raphson method The method is applied for the simulation of the magnetic field distribution in a three-phase transformer.
