Hi Guys
I am new to the Ansys simulation. All the image is enclosed.

General Problem: I am trying to simulate the flow over the vane. The vane is made of elastomer. Due to water flow, the vane will be deflected.

I have a few questions.

A. I tried to Import the above figure in the Ansys by converting to IGES (using Solidwork). But during meshing, it shows the one surface body itself. I couldn't able to separate or suppress fluid domain and solid domain. Any solution how can we do it? Using a single surface body, I cant able to perform the boolean operation. To solve the problem, I had created a fluid domain and later on the solid domain in solid work and imported them respectively overlapping each other. Is it the right way to do?!

B. I am using the transient Structural Analysis system for the solid domain. When I clicked on the analysis setting and clicked on loads, Fluid-Solid Interface is greyed and can't be used anymore!. Is FSI cant work with the 2D figure internet suggest something to use 1 element thick assumption. What is that? How can I use that?

C. I am also missing the Coupling from my workbench, I tried to reinstall it. but I couldn't see it.

You do not say which CFD application you will use (CFX or Fluent). Unfortunately, up to about CFX Release 17.0 there was a Fluid-Structure Interaction tutorial very much like your geometry. This tutorial is still available in the ANSYS Customer Portal so you should have access to ANSYS Support for that unless you have a Student licence. This CFX tutorial is absent in the newest CFX release unfortunately. I recommend you do this CFX tutorial first as you will be able to adapt it to your scenario. There is also Fluent FSI tutorials but I am a CFX user so I have not looked at the Fluent documentation.
