Can anyone please check my COMSOL simulation on a simple microfludic device?

In my comsol simulation, I am trying to form an ultrasonic standing wave field, hence the study that I am using is the frequency domain study. The resonant frequency of PZT-8 is 960 kHz. While running the simulation, I got a really small pressure acoustic wave field. This might be due to a number of reasons:

1. Wrong or missing boundary conditions
2. The material that I am using for the transmission layer between the transducer and the fluid domain

3. There is no coupling between the piezoelectric effect + structure mechanics (solid) with the fluid domain.

My flies are in this dropbox link

Please have a look at my simulation and the brief report. Please tell me whats wrong with it.

P.S. I am using a Classkit License Comsol Multiphysics V5.2, hence I have given the brief report for you to check if you cannot use the Comsol version that I am currently using.
