Efficient evaluation of forward and inverse energy-based magnetic hysteresis operators
Herbert Egger, Felix Engertsberger, Andreas Schafelner
The energy-based vector hysteresis model of Francois-Lavet et al. establishes an implicit relation between magnetic fields and fluxes via internal magnetic polarizations which are…
On the vector potential formulation with an energy-based hysteresis model and its numerical solution
Herbert Egger, Felix Engertsberger
The accurate modelling and simulation of electric devices involving ferromagnetic materials requires the appropriate consideration of magnetic hysteresis. We discuss the systematic…
A semi-smooth Newton method for magnetic field problems with hysteresis
Herbert Egger, Felix Engertsberger
Ferromagnetic materials exhibit anisotropy, saturation, and hysteresis. We here study the incorporation of an incremental vector hysteresis model representing such complex behavior…
A parallel-in-time solver for nonlinear degenerate time-periodic parabolic problems
Herbert Egger, Andreas Schafelner
A class of abstract nonlinear time-periodic evolution problems is considered which arise in electrical engineering and other scientific disciplines. An efficient solver is proposed…
