WebI have compared Femm with Jmag, Ansys Emag and Ansys Maxwell on harmonic analysis of solid rotor induction machine with non-linear BH curve and eddy current. Femm, Jmag and Ansys Emag give the ... WebJan 23, 2024 · Given the original curve spans the second quadrant, the curve should be translated along the H -axis by abs (Hc). When doing so, the input B-H curve will start at (0,0) and reach the remanent flux density Br at the value abs (Hc). Further instructions can be found in the AC/DC Module User’s Guide.
