how to choose FSI for transient structure>fluid simulation
 
Hi,

I found the default FSI is fluid>structure, but what I want to simulate is reverse. Does anyone have done this before? Hope to get ur advice.

Regards,

FSI is a two way interaction between a fluid and solid.
If you give more details about what you're trying to simulate, we could help you better

Hi,

My project is a valveless pump which has a diaphragm driven by a sine force. What I want to get is the relationship of fluid flow and force. So I suppose there are two simulation systems, first is about the deflection of diaphragm to the force and the second is the fluid flow to diaphragm deflection.

This is the first simulation. But I cant connect this result as the setup of FLUENT simulation.

Use System Coupling. See the oscillating plate tutorial in the doc under Workbench > System Coupling.
