I ran the homework simulation and received an error message yesterday, so I carefully re-configured and ran today and got the same error: “An error occured while projecting a field because of an empty node list. If you use a contact with an active position tolerance, please check the tolerance value and increase it if necessary to avoid an empty contact definition.”
please check again your contact definitions (faces assigned in your project) as well as the boundary conditions. As far as I can see the symmetry BC has not the correct faces in its definition (see picture).
Carefully read the instructions in the Workshop post and everything will be fine
If you need help just let me know! Hope you enjoyed the Workshops so far - your feedback is much appreciated!
I decided to start from zero – the OnShape model and work my way through. The new model that I imported and meshed is slightly different the original. Hopefully, that is the problem.
It is now running the simulation, so, maybe, in an hour I might know something. It started at 18:20 EDT or 00:20 hrs your time. Mean time wish me luck.
You may want to hold your analysis until I know something.
Got it to run, but aborted due to time limit [after 64 minutes elapsed time].
Got the following messages:
The computation was canceled either by a user request or due to the maximum execution time being exceeded. Trying to recover intermediate results.

An error appeared during the calculation, please inspect the solver log or contact our support for further information.

The specified maximum runtime of the job was exceeded. The simulation run was stopped and potential intermediate results were restored. You can increase the maximum runtime in the simulation control section to enable a complete simulation run.
Call off the hunt for the problem – I read on the forum that another student was having the same problem as I have.
The recommended solution was to change the Friction Penalty Coefficient from 1E13 to 1E10 and it should work [in less an one-half hour]. I TRIED IT AND IT WORKS!
Thanks for all you efforts. I REALLY appreciate the help.
