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

Hi Deep,

I am new user for Motion solve.I  have face the same problem and try to implement your solution. However, I cant able to open the file in Hm.Can you Please let me know how to open Motion solve file in Hypermesh. In order to  edit as per your suggestion.

Also, Request you to let me know how to export Nodes (points) to  Motion solve from Hm.

I've looked in the manual for this without success.

Just what is a properly meshed model? Must all geometry be meshed, or only that which comes into contact? Are shells allowed?

Where does the manual tell us what the contact mesh needs to be?

Thank you very much.

Phil

I found it!

In the MotionView User's Guide, in the Tutorials, in the Contact Simulation tutorials.

      MV-1010: 3D Mesh to Mesh Contact Simulation

It outlines the mesh requirements and has a link to best practices for contact modeling.

The link takes you to:

       MotionSolve > User's Guide > Analysis Tips: Best Practices for Running 3D Contact Models in MotionSolve.

 

Have fun with it colleagues!

Phil
