Formal Sensitivity Computation of Magnetic Moment method Applied to Linear Ferromagnetic Materials

摘要

This paper presents a methodology forcomputing formally sensitivities of the moment method in the linear case. This numerical method is known to be very accurate and light to compute force and torque in radiated magnetic devices. We propose an approach allowing to compute formal derivatives with respect to the geometrical parameters of the device. Once the sensitivities are obtained, gradient based optimization algorithm can be used.
