Not sure if you need the density based solver, pressure based is good to about Mach 5 if you use the pressure based coupled solver. Historically we switched to density based at about Mach 2-3 but that's changed with the more recent builds. n0.5M cells doesn't tell us if the mesh is dense, or whether it's focused in the right areas. Look at variable plots, as suggests, are these level? Also try reducing the Courant Number and time step. You're resolving the flow in time and space with a transient run. n
