Rookier New Member Ramesh Join Date: Jun 2018 Posts: 8 Rep Power: 7	Hi everybody, I am simulating flow past the NACA 0012 airfoil. The mesh for it is unstructured trias. The quality is pretty good and the number of nodes is also proper. The solution seems to converge but I get cl and cd values near to 20 for zero angle of attack which is much higher than the actual experimental values. Is it possible that my mesh is responsible for the error? Thanks in advance, Rookier
