Hello,
Please refer to the system coupling users guide Participant Variables and Quantity Types Supported by System Coupling (ansys.com).and Mechanical user guide Variables Available for System Coupling (ansys.com).

I recommend going over this tutorial in the Ansys documentation that shows a 2-way FSI simulation with Fluent and Mechanical. https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v221/en/sysc_tut/sysc_tut_reedvalve_fluent.html

 If the structural model is simple, you can use Intrinsic FSI which is an FEA solver built into Fluent. The tutorial is here: Chapter 25: Modeling Two-Way Fluid-Structure Interaction (FSI) Within Fluent (ansys.com)Â
