Hi,

I have modeled piezoelectric transducers on pipe of 1m length in COMSOL and given an electric potential. I am observing the signals(wave packets) at the receiver transducer.

I have used Solid mechanics and Electrostatics for the piezoelectric transducers.

Now I want to observe the effect of fluid on the signals received. I have tried fluid structure interaction but don't know if it is the correct way.

How to proceed with it?
