Comparison of the Finite Element Method and High-Order Isogeometric Analysis for Modeling Magnetic Vector Hysteresis

Modeling the full vector hysteresis relation provides critical insight in the magnetic behavior of the core of an electric machine. Yet, including a vector hysteresis model comes at the cost of a significant extra computational load, that grows with the size of the electromagnetic problem. Therefore, high-order methods, which achieve similar accuracy as the well-known finite element method for a smaller problem size, are potentially very interesting when modeling vector hysteresis.
