Two PZTs, each one as an actuator and a receiver

I want to simulate a structure ( for example a metal block) with piezoceramics on both sides of it. One of the PZT sends the signal and the other one receives it. I don't know how to mount the PZT properly with glue in the structure, how to send sine waves from one side using piezo and how to receive the signal on the other PZT. I am new to COMSOL and I want to learn it to do similar tasks in the future.

There are multiple examples in the application gallery; for example https://www.comsol.com/search/model?s=%20piezoelectric. You will find explanations and sample files.
Many of us (including me) begin by assuming that the piezo is ideally bonded to the object. It is possible to model the effect of a glue if you know the properties of the glue.
