Hi, 

Core resistivity is basically 1/conductivity which we found to be around 5*10^-5 S/m for our most resistive core. We measured resistivity based on a custom-built setup verified with literature reported experimental values. I have already enabled eddy effects for the winding (Copper).

So per your suggestion:

  1. Integrate ohmic losses over the volume of the copper winding to get eddy losses of the winding - then check for skin effect.
  2. Add skin effect based meshing if necessary
  3. Input my experimental value for conductivity of the core (highly resistive as mentioned above). 
  4. Attached is the geometry of my inductor (Core + winding). If I enable eddy losses in the core, and turn off core losses - then probably integrate EM losses over the volume (not divide by the volume (i.e) not calculating density), will that be a good metric? I will search the maxwell help as you suggested but just making sure I understood what you said. Thanks for your time and patience!Â
