I work with induction heating and I was looking to the equations in order to increase my comprehension (I am a mechanical engineer) and I am blocked on the time-harmonic quasi-static formulation.
In attached file, you can follow the equations flow. You will see that I have a portion of the equation that Comsol get rid of. Unfortunately, I don't understand why. From how it is explained in the doc ( ACDC user guide 4.4 p.33), it would be caused by the hypothesis of being in quasi-static case. But, what does it implies (in the equation)?
Thank in advance for your help!

I found the answer in the doc at page 235-239 of ACDC 4.3 guide (256-260 for version 4.4).
Basically, if I understood well, it is simply caused by a gauge transformation that makes (σ+jωε)∇V disapear.
Best regards,
