Inclusion of an Inverse Magnetic Hysteresis Model into the Space-Time Finite Element Method for Magnetoquasistatics
Mario Gobrial, Lukas Domenig, Michael Reichelt +2
In this note we discuss the numerical solution of the eddy current approximation of the Maxwell equations using the simple Pragmatic Algebraic Model to include hysteresis effects.…

On energy consistent vector hysteresis operators
Herbert Egger, Felix Engertsberger, Lukas Domenig +2
Incremental models for magnetic vector hysteresis have been developed in previous works in accordance with basic principles of thermodynamics. In this paper, we present an equivale…

On nonlinear magnetic field solvers using local Quasi-Newton updates
Herbert Egger, Felix Engertsberger, Lukas Domenig +2
Fixed-point or Newton-methods are typically employed for the numerical solution of nonlinear systems arising from discretization of nonlinear magnetic field problems. We here discu…
