Hi, @smlbysl 18.2 is a bit old and we don't support this version any more. Could you try opening your project in a newer version and see how the core loss result goes?
For hysteresis core loss model, even if "Defined in Material" cannot be checked, as long as you check "Core Loss Setting", you will be able to get core loss in result transient report.
You can also check if your time step and stop time is too large compared with the period of your AC signal in your excitation, this can result in zero core loss in result.
