Abstract: Finite element method (FEM) of nonlinear magnetic field computation embedded with different vector Jiles-Atherton (J-A) hysteresis models is investigated in this paper. Newton’s method is adopted to do the nonlinear iteration. Both scalar and vector J-A models are incorporated into the FEM computation. The TEAM workshop problem 32 is used as a numerical example. The computed results are compared with the measured ones, which shows the effectiveness of the developed algorithm. The specifics of different vector J-A models are pointed out from the viewpoints of modelling accuracy and convergence performance.
Keywords: Finite element method, Jiles-Atherton model, Newton’s method, TEAM problem 32
