ACDC Frequency Domain simulation with two different frequencies

Hello,

I am trying to simulate two resonance circuits using the ACDC Module. How can I simulate the system in the frequency domain considering that the voltage sources of the two respective circuits have to operate at their respective resonant frequencies?

As I understand, the frequency domain simulation of COMSOL imposes the same frequency on both the circuits but I need the voltage sources of the two respective circuits have to operate at their respective resonant frequencies.

Any help would be much appreciated.
