Please, how to bring highfrequency AC to the capacitor plates?

Hi

for example if you solve in frequency domain (harmonic development of the equations) then you set the amplitude in the BCs and the frequency freq in the solver settings as an unique or a range of values.

Note, take care to respect the ACDC conditions, frequencies sufficient low such that the wavelengt is much bigger than the domains you measure on, else you should use the RF module for "really" high frequencies GHz or optical

Check the doc and the model library too ;)

Good luck

Hi Ivar,
thanks for your reply. Please, I describe my problem in subject Diathermy heating.. Is it possible to use RF module?
