the message that you mentioned only means that an error happened (basically whenever the exit code is not equal to zero).
The actual error comes from the use of the bonded contact.
I’ll have a closer look why this error could actually happen.
In the meantime you can work around this by setting the position tolerance to off. In your case it won’t influence the results anyways.
If you re-run your analysis will proceed a little further but you will get a different error stating that you have some nodes common on multiple slave definitions of your physical contact. If you remove faceGroupOnGeoFaces_68 from the slave side of contact Connection 3 it should at least proceed to start with actually solving the system.
