We present the open source micromagnetic framework, MagTense, which utilizes a novel discretization approach of rectangular cuboid or tetrahedron geometry "tiles" to analytically calculate demagnetization field. Each tile is assumed be uniformly magnetized, and from this assumption only, field can calculated. Using we solution mmag standard problems 2, 3 4 find that MagTense framework accuratel...

In this paper, methods for finding the demagnetization factor, specifically permanent magnets, are considered and compared. Widely applied cited literature expressions compared to high resolution numerical modeling in order establish applicability of expressions. Overall, found be very closely correlated with results. second part, a simple geometrically based method find factor is proposed Fair...
