A new convergence procedure for the finite element computing associated toPreisach hysteresis model

This work presents a convergence procedure in electromagnetic computing pro blem taking into account hysteresis. It is based on separation of magnetic field into two parts, applied and demagnetization ones. The ferromagnetic h ysteresis is described by Preisach model. This model is integrated in finit e element method (FEM) in order to resolve magneto-dynamic problems. Conver gence problem around critical zone of hysteresis curve is resolved within a n iterative algorithm. In addition, an optimal relaxation parameter is dete rmined.
