I am designing and analyzing an air intake. I'm running at subsonic speeds. I use k-sst standard and density based solver. I preferred the Implict method. I have 60k gage pressure at the entrance and exit, but my operating conditions value is 0 Pa. I tried the solution in many ways, but after a certain number of iterations, I get the following warning. To prevent this, I tried adding the double process option and reducing the courant number, but this time, all graphic values except k and omega are stable and I cannot get the right solution. Do you have a solution for this?

Hello, 

can you try with the pressure-based solver?

[Enes Bitigen]

I have an inlet value above the 0.3 Mach limit. At the same time, I'm working with an ideal gas at 250 degrees Celsius. I'm not sure if I can obtain accurate results using the pressure-based approach.

Unless you are working with Mach numbers in the hypersonic regime, the pressure-based solver will do just fine.

When I make a pressure-based solution, it takes 250 iterations and the results are not as they should be. This is an analysis situation that does not yet yield results in 5000 iterations when making a density-based solution.
