I am new to Ansys/CFD and have some questions about my convergence plot shown below.
For the beginning an ideal gas in a pipe was simulated with following parameters:
diameter: 0.1 cm
Inlet speed: 125m/s
relative pressure outlet: 0 Pa
Is my result already "okay"?
Do I have to improve any settings, for example mesh, to obatin better results?
Are more iterations steps necessary?
I know, that the pipe is too short to reach a fully developed flow profile. Does this affect my convergence?
Thanks in advace,
But this is only a guess... I do not have much experience with turbulent flows. So you better wait for someone who is qulified to confirm this =)

Just to add to that above. You should also check the various imbalance percentages at the end of the out file.
