摘要：
This work presents a convergence procedure in electromagnetic computing problem taking into account hysteresis. It is based on separation of magnetic field into two parts, applied and demagnetization ones. The ferromagnetic hysteresis is described by Preisach model. This model is integrated in finite element method (FEM) in order to resolve magneto-dynamic problems. Convergence problem around critical zone of hysteresis curve is resolved within an iterative algorithm. In addition, an optimal relaxation parameter is determined.
