I have made a model using electromagnetic heating in which I calculated the heat produced due to electromagnetic wave flux using single frequency input. Due to memory limitations set by maximum mesh size in this case, I used 10*10 um xy dimensions whereas the original are 5*5 cm. My questions are
(a) How can I use multiple frequencies as input to calculate collective heat produced?
(b) How can I add symmetry boundary conditions in xy dimensions?
Thanks

Regards

You can use frequency as parameter (Frq) sweep function for simulating multiple frequencies. However in heat transfer module you need to disable multi physics coupling and manually set the heat source in the heat transfer module as
sum(withsol('sol2',emw.Qh,setind(Frq,i)),i,1,No_frq)/No_frq
Keep in mind you need to replace solver tag 'sol2' with parametric solver tag.

No_frq is number of frequencies you sweeping.

Set two study separately for RF and heat transfer module.

Hope this help.
