The freestream conditions are:

• Mach number = 0.729
• Angle of attack = 2.31 deg.
• Reynolds number = 6.5 million

## Sample results

The following results are from a vertex-centered finite volume code which uses Spalart-Allmaras model. The grid is taken from the NPARC Alliance web-site and consists of 23952 vertices and 47104 triangles. The $y^+$ for the nearest vertices is less than 3.

### Pressure coefficient

The pressure coefficient on the airfoil surface is compared with experimental results.
