"Simulation : Failed" when using countersunk screw 'bolt connectors'

I'm trying to simulate what would happen when a bar is clamped between two spinning rotor discs.

 

Here's the assembly I'm using:

It's a 7.5° 'slice' with circular symmetry applied.

 

I've added two countersunk screws - one either end of the bar - and applied a torque preload to them.

 

Every time I try and run the simulation, within a few seconds it just stops and says "Simulation : Failed".

 

I was experiencing this error on another more complex model, so I created this simplified version to see if it was a problem/corruption in the files I was using. But the issue with the bolt connectors remains.

 

If I get rid of the bolt connectors and use something else (e.g. a rigid connector) the problem goes away and the simulation runs OK.

 

I've attached the assembly in the hope someone might be able to find out what's causing the problem.

 

Thanks for your help,

 

Chris
