I have simulated High Frequency Transformer (HFT) in Ansys Maxwell 3D transient analysis. The corresponding simulation details are given below:

Hi May I ask what you mean by saying "I didnÔÇÖt get the temperature rise"? If environment temperature is set at room temperature (22 C), then from your temperature graph your object temperature is above 40C which shows some temperature rise after importing heat loss.
The loss mapping may not be performed well. Could you expand the imported load tab and check the scaling factor of loss mapping? It should be very close to 1, otherwise it's not good mapping and you may need to add finer mesh in workbench to get better loss mapping.
Is there a specific reason you chose steady state thermal in workbench? You mentioned "as constant and not varying with losses and time", if you'd like to see temperature variation with time, I'd recommend using transient thermal rather than steady state thermal in workbench.
Are you interested in the feedback effect: maxwell loss-->workbench get temperature-->feedback to maxwell: calculate new loss based on temperature dependent conductivity in materials in maxwell-->insert loss to workbench to get new temperature... iterate? You need to enable thermal modifier and set object temperature if you are interested in feedback effect, if not, there is no need to set these in maxwell. Please let me know if I'm understanding you correctly.

Yes icellb1.
Thankyou for your reply. Your explanation is clear to me. I have reset the atmospheric temperature as 40degrees. I have given that as initial temperature in in ansys also. Imported load scaling factor is nearer to unity as shown below.
I have one more doubt. here I imported heat generation from 0.01sec to 0.015 sec done in maxwell. Analysis time is predefined as 1 sec (not able to edit for me).

Thank you once again for the reply. I will go through your suggestions.
If possiible consider above cases also
