I am using SW on a 30 day trial.  How do I report a problem?  Something appears illogical so I assume it is a bug.  The "Visit the Knowldege Base for further assistance" does not have an answer.  I had trouble with a simulation model failing to run after I added more details. The error message was "File-based iterative solver interface is not supported by a large displacement solutions".  The model ran perfectly until I added an extra mesh control to the 3 that had previously run without issue.
