Electrical circuit around a beam.

I have a aluminium beam with a piezoelectric patch at its center. The beam is loaded by a harmonic force. I have modeled this and the loaded beam shows expected results both in terms of displacement and potential across the patch. The patch on the beam behaves as a voltage source. Next, I need to build a electrical circuit around it having a load resistance which I believe will cause the damping of beam vibrations due to conservation of energy. But I couldn't find a way to do so in COMSOL. Is there a way to do simulate this structural-electrical circuit in COMSOL?
