I am doing MV-1010-contact simulation tutorial of geneva model. When i checked the final model the page prompted an error in the model as:

"Error:   Contact Crank_to_slotted under Model from HM references one or
              more graphics that contain free edges, i.e. the geometry is not
              closed, or T connections.   The graphic(s) in question are: Crank,
              Slotted Disk.                                                     
              Open shell graphics or graphics with T connections are not allowed
              in contact simulations.  "

I think i need to delete or merge free edges, but i don't know the procedure for doing that. Please help me in solving this issue?

Hello Abhishek

when you are doing contact simulation in MotionView you should have properly meshed model

so Use Hypermesh to mesh it properly then go to tools>Edges> Check for free edges and T connection

If you found Free edges or T connection you have to remove it. Your geometry should be completely closed
