I've been trying to run a therm file which at first displays a single red circle that changes locations every time I try to fix the point where the red circle is (I've encountered this before, but with just a few fixing and running the file eventually runs successfully). However, after a few fixing and running of the therm file, a window appeared which said
"The geometry contains voids or overlapping regions. The edges surrounding these regions will be highlighted in red. You must fix this problem before simulating. Regenerating Boundary Conditions may correct this in some cases. There are materials that lie outside of the Boundary Conditions."
After this message, red circles have appeared all over the perimeter of the model. I have tried fixing the model but there is no luck. This is the first time that I have encountered this. Does anyone know how to solve this problem? Is this just a software glitch? If so, what should I do? Please, I need your help asap as I need to submit the thermal analysis report tomorrow.
