    One or more load/fixture/contact/connector associated entities may not be valid.

      Hello,

       

      I'm trying to simulate various worst-case loads on a vehicle frame made of composite panels. I had no problems assigning the materials, and it meshes fine. But when I try to run a simulation, I keep getting the error:

       

      "One or more load/fixture/contact/connector associated entities may not be valid."

       

      I keep getting this on several different loading/fixturing scenarios, and I can't see anything wrong with the contacts and connectors. Can you give me advice on what to try, or what could be wrong in the model?
