Abstract :
In this paper a 2D Finite Element procedure devised to handle both soft magnetic materials and hysteretic ones, on basis of Preisach´s classical approach for scalar and vector hysteresis, is presented. In the scalar case, a model identified by a reduced set of experimental data is proposed, whereas for the vector case a more demanding identification procedure is required. The resulting modular “Preisach engines” are used to solve some problems of practical engineering type
