Working on a first "real" simulation. I was surprised at how thin the layers at the rocket surface needed to be to get to a y+on the order of 10. I also wasn't very successful in getting multiple polygon mesh refinements to work like you had done. I could get one box inside the main model, plus a "distance form the rocket surface" one to work. Finally, I just love it when residuals do this kind of thing. It is still working, so we'll see what it comes up with. The domain is 1500x1500 with a 100mm-diameter rocket, so we're looking at ~0.4% obstruction.
This solution is blowing up, most likely from the mesh. Are you running steady state, or attempting transient? Residuals really have no meaning in a true transient flow. They will level out and oscillate without dropping orders of magnitude. Your residuals are not doing that, though. Your simulation is all over the place and diverging. (I tried a transient run, and the CfdOF parameters are pretty sparse. Will need to tune the settings in the OpenFOAM dictionaries to get a good blend of accuracy/efficiency.)
Anyway, a nicely converged steady-state solution is feasible. I changed my convergence from 1.0E-03 to 1.0E-04. No troubles.
