Hello CFD Community,

How do you perform a transient simulation on an electrical component with AC current as source of heat.

Still i do not know how rms power gives temperature field similar to transient case. If you have something please share.

RMS isnít really relevant to your problem unless its average power from AC electrical waveforms.
