For the coupling you need to have a fracture already present as we can't alter topology in the FSI function. Also, until the fracture has a finite thickness there's nowhere to put the mesh. 

In terms of modelling how much/big a fracture is, you may need to review the FSI materials: it's an area I've modelled in once to prove how easy Workbench was in R13! As you're looking at sticky spheres the new Rocky material (went live this week) on Learning will also be of interest.
