If you mean you want to model the particles as meshed entities in Fluent then you will need to export the surface from Rocky and then volume mesh the fluid parts for Fluent. That's potentially difficult and computationally expensive. I'd advise reading up on Fluent Meshing's Fault Tolerant Meshing and the Wrapper. 

The coupled solution is likely semi-resolved. So, set Fluent up as normal for Rocky coupled flows (there's a tutorial) and also review the semi-resolved options.
