Abstract :
Most magnetic materials have nonlinear hysteresis phenomena. In this paper, the efficient combination of the finite element method with a hysteresis model is presented. A magnetization-dependent model is employed as a hysteresis model. Finite element formulation is derived from the modified constitutive equation. This method removes the additional computational cost such as calculation of the residual magnetization and shows good convergence with short calculation time
