Hello 

Not all fluid surfaces (here lubricant) should be surrounded by solid but the interfaces across which data is being exchanged between participants should overlap.

You can refer to the results of a tutorial and understand how the coupling interface placed to exchange the data between the interface: Reed Valve FSI Co-Simulation with Partial Setup Export from Workbench (Fluent-Mechanical) (ansys.com)

To visualize mapping on interfaces in Ensight refer: Evaluate Mapping Quality (ansys.com)
