Reply To: ANSYS Maxwell Calculating Core Loss in Transient Mode with Strange Deviation

[Francoo]

I get it! It is indeed a bug in Maxwell. When the core loss model is "power ferrite", the method in transient mode is equivalent elliptical loop (EEL) method. In the original version of EEL, coeffienct beta (namely Y in the software) should be 2 to form an elliptical loop shape. Yet, the EEL literature also proposes a general solution when beta is not 2, which is neglected by the ANSYS.
So, if I change the Y here to 2, the results are correct......
