Yes, there are thin faces and geometry but the interesting thing is that the frame at the front that doesn't allow me to mesh as one body anymore has identical geometry as the ones in the middle. Therefore, it's weird why it can mesh individually but won't mesh as a whole. Is there a limit to the size of a body or number of elements Ansys allows on a singular body? (Nothing regarding exceeding number of elements popped up though.) I have already tried turning defeaturing off and it still doesn't work.
