Hello,

I am trying to simulate the turbulent flow around airfoil NACA0012 at low Mach number (say M=0.15) and Re=6e6 in order to perform a shape optimization, then I also need adjoint simulation (impossible with the incompressible formulation, is it right?).
Up to now, I don't have a satisfying enough solution in terms of pressure distribution. I have some questions:

• Do you have any advice to build a good mesh? My mesh: http://www.4shared.com/zip/8Zgpycw1/...12_40ksu2.html.
• From your twitter account, I notice that you are validating low Mach cases. Do you have any suggestion to run my case? (space and time discretization, multigrid…)

Thank you in advance,
Roberto
