1). Could you check if you have other solid losses except for the inductor? Solidloss is total solid loss in the model.
We could check eddy effect, or integrate Ohmicloss in the inductor object in field calculator.
2). Addtionally, this solid loss would include the AC loss. Do you check if you have big AC effect on the inductor? The AC loss would not be proportional to I^2. Thanks.
