The supersonic outlet is not a proper BC as you have just a small supersonic region around the airfoil but not through whole domain. Outet is the best, but you may be able to use opening, as well....

Thanks again Glenn.
The convergency problem was because of the poor quality mesh around the foil and it got solved. I changed the mesh from C to O to keep the boundary layer elements refined while...

Fixed transition airfoil
