I am trying to model a piece of alloy heated by high-frequency induction heating, and there appear to be two ways to model the eddy current losses.<\/p>\n

1) eddy effects – this results in the core loss pattern (and thus temperature distribution pattern) that I would expect to see for the geometry of the system, but it appears to be independent of frequency (eddy current loss should be proportional to f^2) and gives me losses that are far less than expected. (TOP IMAGE)<\/p>\n

2) core loss – this method is definitely proportional to f^2, but removing the eddy effects as suggested when activating core losses means that I no longer see the expected distribution of core losses. (BOTTOM IMAGE)<\/p>\n

<\/p>\n<\/p>\n

I guess my question is, how are the losses being calculated under eddy effects if they're not dependent on frequency? How can I get an accurately frequency-dependent loss calculation that also still incorporates eddy effects to get the expected distribution pattern?<\/p>\n
