Using Quasi Static Analysis to simulate ASTM F382 Test of Bone Plate

I am trying to recreate a bench test recommended by the FDA for bone plates in ASTM F382 Standard Specification and Test Method for Metallic Bone Plates. The loading rollers should apply a force until the plate deflects ~0.024mm. The simulation should record the reaction of the plate throughout the simulation.

I have set the loading rollers and supports as rigid bodies. All components have materials from the non-linear library. I have tried various scenarios constraining each body, applying a load and applying a prescribed translation but I keep getting errors. The two most common errors I've received are attached.

Given that an anatomic bone plate doesn't have many straight lines, there are no parallel surfaces between the plate surfaces and the rollers/supports. Is that why I'm hitting a wall?

Otherwise, I would like to confirm that I set up the simulation correctly.
