Hello everyone,
I am a new user of COMSOL. Now I build a simple beam with a PZT patch at the fixed side. I have two question here. 1. When I add a circuit at two side of PZT, the eigenvalue solve can not take circuit into account. I can only get the eigenvalues in the no circuit situation. Is that because it will two coupled system when I add a circuit to the PZT patch? 2. Is it possible in COMSOL for me to select several modes in a time independent study? I just need the sum of first to third or fifth modes of vibration of the beam. If you guys need any documents of my model please let me know. Best, Yixin
