3D Displacement for Pressure Input

I have a relatively complex ultrasonic model of a transdcuer. I can run the model for satisfactory results to obtain information regarding impedance and stresses/displacement on the device. However, my challenge is trying to then couple this device into a pressure acoustics medium, gas (too large to compute), to observe the pressure output of the device in either the time or frequency domain. My model has the additional challenge of being symmetric in only one axis also.
My question is, can I take information from the initial transdcuer simulation relating to the 3D front face vibration and then use this information as a pressure input on a pressure acoustics physics simulation?
The idea being to keep the models related but decouple the computation of the physics processes.
Cheers

You can do that, and probably in different ways. You should be able to take the displacement from one study and use in the next study. Look under Values of Dependent Variables and change the settings for Values of variables not solved for, to get started towards a solution.
