I'm validating previous data for my project but when I try to run the simulation for a total pressure of 101325 and total temperature of 300k, I don't get the exact results. I don't know what I'm doing wrong. kindly help me

Hi,
Your simulation is not converged. The flow I see really doesn't seem reasonable, and I don't even know what you are simulating. I just does not look good at all. Does it make sense to you? What are those magic stripes you have in the Mach number on the bottom right? Why is the pressure like this? Do you expect that? |

I'm trying to simulate a CDC nozzle with a domain to observe the flow at the exit area. Yes, I know it isn't making any sense. I'm a beginner in CFD that's why I don't know what I'm doing wrong as I have followed all the steps properly. I would really appreciate your help.

I would run the simulation for more iterations. As I said your simulation is not converged
