NLF0416 at M=0.69, cann't get convergence

Chen Yi

I want to make a computation of NLF0416 airfoil with SST k-omega model in FLUENT.

The far field boundary conditions is as follows,

M=0.69 Re=4.0e6 Tu=0.3% Rt=5

But I can not get a converged solution, even I set the Courant No. as 1.0

I hope someone can help me. There are the 'cas' file and the grid 'gg' file.

I hope someone can have a trial with my grid and my 'cas' file in FLUENT and tell me what is the problem with my computation.

Thanks a lot!!!
