Dear CFD buddies,


I'm simulating a supersonic inlet by increasing the back pressure ratio. Till the the back pressure ratio of 4 at the interval of 1 I was able to generate results. When I'm simulating for back pressure ratio of 5 I couldn't solve and AMG solver is being detected.

Tried refining the mesh- didn't worked

Settings:
altitude:30km (corresponding P, T values)
Mach :2.18
Desnity based solver
Spalart–Allmaras turbulence model
Explicit solver
courant number -0.5

Hope I could find the solution.
All suggestions are accepted
