Nick R Senior Member Nick Join Date: Nov 2010 Posts: 126 Rep Power: 15	Hi All, I'm simulating a 3d airfoil in cfx using icem mesher. I have a problem in cfx solver, I either get negative volumes or floating point overflow errors. It's very frustrating as I've changed things around many times to no avail. Could mesh orientation cause these errors? I mean if you have some right-handed and some left-handed elements would the solution fail? Also how can I get rid of negative volume elements? Many thanks. Nick
