Set the air viscosity for something about 10^-15

Thanks But the wall condition is no-slip boundary condition which is different from the Euler solution.

Do not set the air viscosity to 10e-15. This will make the Reynolds number huge. You actually need to adjust the viscosity such that you get a Reynolds number around 1000 (the code works best for this type of case around this Re number). Set all your walls to free-slip and use the Laminar (None) as the turbulence model. Also use BC's that do not introduce any rotation into the flow, so Total Pressure inlet and Static Pressure or Mass Flow outlet. Mike
