MauroTortora New Member Join Date: Nov 2020 Posts: 3 Rep Power: 5	Hi to everyone, I am meshing a centrifugal fan with TurboGrid. The trailing and leading edges have a cut off, therefore I have included this feature in the geometric representation of the blade. However I get this error: The selected topology templates did not result in a valid topology. Please refer to the following messages for more details: Thread 1 failed at index 1 with message: Round off problems. Last Edge length too small=1.41101e-08, #of segments 51 Can anyone understand what it means? Thanks in advance, Mauro
