Hi, I have noticed that while chooing BH data from tab file it is madatory that first point value is ZERO for both B and H. Does this mean we need to use Virgin curve or Intial magnetization data of BH rather than usual hysteresis test data?

Hello, hysteresis BH curve could be used, which solver are you using?

I am using magnetostatic solver.

Transient solver will allow using hysteresis (descending HB half curve+Kc)

• Descending limiting branch of hysteresis loop + Kc
• Recommend BH curve ± 3T maximum
• Start and end points: (-B,-H) and (B,H)
