I am getting errors in simulation

[mwhines5]

Hello, 

I am trying to run a simulation on two components but the simulation isn't working. 

The simulation comes up with these errors: 

Warning: Warning: Some components/bodies in the Simulation Model have interferences
Click here to switch to 'Simplify Environment' and open 'Interferences'.
Warning: Warning: Visibility is turned off for some Bodies or Components. Hidden Bodies and Components will still participate in the Simulation Solve. To exclude Bodies and Components from the Simulation Solve, use the "Remove" tool in Simplify workspace.
Warning: Warning: Model contains 1 fully unconstrained group(s) in load case "Load Case1".
Click here to select 'Automatic Contacts'.
Click here to select 'Manual Contact'.
Click here to select 'DOF View' to inspect.
Warning: Warning: "Bolt Connector1" may be in conflict with "[S] Bonded1 [Clamp (1):1||Metal Stage:1]".

I have attached the file bellow. 

Cheers.

Hi @mwhines5 

Did you eliminate the interfering bodies? "Stage:1 > Bodies > Body1" occupies the same volume of space as "Stage:1 > Metal Stage:1 > Bodies > Body1". I suspect that "Stage:1 > Bodies > Body1" should be removed from the simulation (if not removed from the model entirely).

If you remove "Stage:1 > Bodies > Body1", that will eliminate the warning about the model containing 1 fully unconstrained part. As the message indicates, "Stage:1 > Bodies > Body1" is not constrained or bonded to any other parts of the model, so it will just "float" away. (Unconstrained parts are not allowed in a static analysis.)

The bolt is not providing much benefit in the analysis because the Clamp and Metal Stage are bonded together. Even if you remove the bolt, those parts are not going to move because they are rigidly connected together. Either remove the bolt and simplify your analysis; or keep the bolt, change the contact type from bonded to separation, and make the analysis more complex.
