How to couple Piezoelectric Devices with Fluid-Solid Interaction

Please login with a confirmed email address before reporting spam

Hello All

I have a confusing problem and i do not know how to solve it. First I want to describe what I want to do and then I will ask my question.

The problem : I have a piezoelectric device which is deforming by applying a voltage . Assume a PZT disc. now I want to put this device inside a tank of water ( laminar Flow ) and redo my test. I want to see the pressure gradient of the fluid triggered by the piezoelectric device.

The question:

I have read somewhere that in order to implement my model , I need to use three physics :
1- piezoelectric devices
2- Deformed Geometry
3- Lamina Flow. or maybe ( Fluid- Structure Interaction )

It means first I need to run the piezoelectric device physics, and based on its solution, run the deformed mesh ( ? ) and eventually use the deformed geometry as an input to my fluid problem. Here is my problem. I actually, do not know how to get the deformed mesh from ( Deformed Geometry ) and put it inside the Fluid problem. It seems like the coupling between ( piezoelectric device ) and ( deformed geometry ) goes smoothly whereas to further couple them with fluid structure interaction is very confusing.

I would appreciate if you could give me some tips and tricks to solve my problem .
