An accurate vector Jiles-Atherton model for improving the FEM convergence
2016
This paper presents some modifications — compared to previous implementations — on the vector Jiles-Atherton (JA) model coupled with the Finite Element Method (FEM). The method is based on the 3D differential permeability formulation. A more precise calculation implies on the determination of the non-diagonal terms of tensor parameters. The main goal is to verify if such a change improves the convergence stability of the model coupled with FEM and if the use of the JA non-diagonal terms yields a more accurate hysteresis representation.
