I'm sure your NUMECA support person can answer that question.

Dear Sunset;
Sometimes negative cells are generated as a result of poor geometry.
review your geometry and try to import a smooth one into NUMECA.
besides that, changing the number of elements or even multi-blocking approach can help this problem. try both!
