confusion on boundary conditions

Hey all, i am trying to building a model to simulate the acoustic pressure in 3D for the ultrasonic cleaner.The component includes multiple piezo transducer, steel tank and water inside. The physics includes pressure acoustic (frequency domain), solid mechanics and electrostatics. I am ok with the domain assignment. When i come to boundary conditions, i am totally lost. In reality, the piezo transducer is constrained at the bottom and tank is fixed on the top.

In this case, what kind of boundary conditions are closed to the reality? The physics selected is good enough to do the job?

Can someone help me with that? thanks in advance.
