help please 1

Hi Guys,
I am trying to analyse a section of a rail track where a wheel having axle load of 250 KN rotating on the I beam. I cannot get the wheel to rotate,the model is not working and I cannot seem to find the problem. Could you please help?
The error is:
Warning: Permission was denied for "abaqus.rpy"; "abaqus.rpy.3" will be used for this session's replay file.
The job input file "Job-1.inp" has been submitted for analysis.
Error in job Job-1: 1 nodes are missing degree of freedoms. The MPC/Equation/kinematic coupling constraints can not be formed. The nodes have been identified in node set ErrNodeMissingDofConstrDef.
Job Job-1: Analysis Input File Processor aborted due to errors.
Error in job Job-1: Analysis Input File Processor exited with an error.
Job Job-1 aborted due to errors.

Any help is appreciated.
Thanks

Open the ODB and check where that set is. It is probably one node. Afterwards check what definitions you have on that node.

In the Interaction module, edit the Constraint-1 of coupling type, and respecify the control point. This point cannot belong to the wheel surface. To specify this point, you must select a point from the rail, or create a point where the wheel and the rail come in contact through partitioning, and then select it for the constraint. However, I couldn't find out what is the purpose of this constraint.

Best regards,

Not especially related to your post, but there seems to be an epidemic of this problem, so I am reposting what I told another poster:

If I can offer another piece of advice. The titles to your posts are atrocious. They sound whiny and show that because you can't even put enough thought into a thoughtful post title, that it us unlikely that you have even put a modicum of effort into solving your own problem yourself.

Do yourself and the rest of us a favour and use a thoughtful and informative post title.
