OAT15A airfoil, hybrid grid. The hybrid grid has 470 points on the airfoil surface, with a total of 29,704 cells (10,824 prisms and 18,880 hexahedra). The viscous layer around the airfoil consists of 40 layers of hexagonal cells extending out approximately 0.05 meters. The far-field boundary extends out 20 chord lengths.The solution was obtained using the Wilcox K-Omega two equation turbulence model..
