Default How to model hypersonic flow

Hi, I am trying to model hypersonic flow around a blunt body. I could go upto Mach number 3.5 after which the solution diverges. Any thoughts please? I am using the following Operating pressure 101325 Pa

If I make the operating pressure to 0 I get floating point error. I am relatively new to CFD and FLUENT.

Thanks, Subramani
