Hello,
I'm a just a recent user of COMSOL and still trying to get my head around some of its features, but learning slowly but surely. I have been trying to model induction heating of ferromagnetic materials such as low carbon steel to temperatures beyond 700 degrees celsius, so above the curie temperature point. I can set up property functions for the materials I am heating up, fairly easily but the one property I have not been able to set up a function for is magnetic permeability, which I know definitely changes with temperature and changes significantly as the material approaches the curie point.
I am curious to know, if anyone else has encountered this problem and found or knows of a reliable way to model changing permeability for materials being heated beyond curie.
Any help or guidance would be most appreciated
