Second-order tetrahedral edge elements afford much better accuracy in magnetic field analysis compared with first-order elements. However, they often entail higher computational cost due to the higher number of unknowns, many of them being redundant.

This paper used a finite-element magnetic field analysis (FEA) to investigate the instantaneous and average power in a single phase transformer and a three-phase rotating machine. We examined the influence of the hysteretic properties of the magnetic

In this paper, we introduce a novel approach for obtaining steady-state solutions in time-periodic magnetic field analyses considering hysteresis. First, we extract the poorly converged error component in transient calculations using the parallel tim
