Combination of hysteresis models for accuracy improvement and stabilised electromagnetic calculations

An interpolation strategy based on pre-evaluated integrals of the first-order reversal curves is presented. The proposed approach allows the seamless integration of different hysteresis models into a single calculation in a way that the most appropriate curve is picked up for particular subdomains of the Preisach plane. It can be shown that this approach can contribute to the stabilisation of numerical field calculations.
