Hi,
There is a parameter in COMSOL 4.2, in piezoelectric simulation, pzd.Y11 which gives you input impedance if you simulate a one port device. I think this correspnds to Y11 parameter of Y matrix. I am simulating a 2 port device (filter) and need to get Y21 and Y11 parameter to be able to calculate S parameters (Y12 and Y11 is not necessary since it is symmetric and reciprocal). I couldnt see pzd.Y21 parameter in the tutorial or help, but when I defined it as variable, it looks it is working if I set the voltage of the terminal 2 as 0 V. When I set the voltage of the second terminal different from 0 V comsol cannot calculate pzd.Y21 parameter, which makes sense to me. I believe that is correct but would like to verify with someone else if anyone tried using such a paramater.
Thanks for the help!
