Hi guys im pretty new here and also relatively new into CFD ,

I have been having some question marks regarding my convergence .

So the current sim that im running at the cluster has 97 Millon cells and I believe a pretty good mesh the wally values are between 0.5 and 3.8 also has grid sequencing initialization.

it is a rocket running at mach 1.2 and I used 25/mach for CFL number. It is running in freestream which has enough gap to propagate the pressure.

But with all these I get this kind of residuals even though the values converge to something Im not sure if the results are reliable or not nor was I able to find some reference wind tunnel paper so that I can check my physics .

Should I post it somewhere else ?
