Hello, thank you for your reply.

I am using the pressure-based solver with coupled method and 2nd-order discretization schemes. I have also tried the density-based solver, but it seems to take many more iterations to get to the same point.
I have attached the contour plots and residuals.
Also, after the shock disappears, the inlet becomes subsonic, which is not what I set.
After fmg initialization:

after 150 iterations:

After 300 iterations:

After 500 :

After convergence:

Residuals and inlet Mach number:

Kindly help, Thanks
