How do you restrain a model without influencing the results

I've attached a simplified version of a part with a force on the O.D. and a Sliding Restraint on a face.  The simulation fails because (I think) is is looking for more restraints.  Question: How do I restraint it and not influence the distortion?  Because the part is dished and has a window cut in it, the dish shape should flex and the center shaft should move away from the Roller/Slider restraint and the axis should tip as indicated by the black arrows.  If I add a fixed restraint the simulation will run but gives a non-realistic result.  Any held would be appreciated.
