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 
for the nearest vertices is less than 3.
Triangular grid and finite volumes
Pressure contours
Mach number contours
Pressure coefficient
The pressure coefficient on the airfoil surface is compared with experimental results.
