I'm sorry if it seems that I'm not patient. But I'm truly patient and trying to provide you with all the details.

what I was trying to say, is that I used ideal gas density but it still the same problem.

I tried to enter the turbulence coefficients randomly( i tried different values) in the inlet and outlet. Yes, there is a change but it has nothing to do with the results that I want to achieve.

I tried also the Hybrid initialization, it gave me the same result.

Best regards,
