Can't find a point that lies inside of a polygon

[Ian Clark]

I am very new to therm. I am trying to calculate and it says can't find a point that lies inside of a polygon, I have checked this and even redone it and cannot figure out what is causing this. After it says this it says "problem in meshing the model", I am assuming this is part of the same problem. My file is attached below.

Thanks in advance.

I was able to get the file to simulate. The program highlighted the problem polygon after the error message was displayed and it was the top plywood layer. I deleted it and recreated it, making it and the aluminum above it the same width. Not sure that mattered but it simplified the model a bit.
