Thanks for responding , Y+ is around 3.3, after i added boundary layers, i will reduce it down to less than 1.

I tried fmg initialization after you had mentioned, it says something like this: 

temperature limited to 1.000000e+00 in 208 cells on zone 2

temperature limited to 1.000000e+00 in 20 cells on zone 2

temperature limited to 1.000000e+00 in 6 cells on zone 2

temperature limited to 1.000000e+00 in 4 cells on zone 2

FMG: Converge FAS on level 5

FMG: Converge FAS on level 4

FMG: Converge FAS on level 3

FMG: Converge FAS on level 2

FMG: Converge FAS on level 1

0.

Reversed flow on 18 faces (100.0% area) of pressure-outlet 5.

Reversed flow on 32 faces (100.0% area) of pressure-outlet 6.

time step reduced in 66 cells due to excessive temperature change

for the pressure-farfiled BC, I can only give mach 0, would that be a logical thing to do? Because, i only have a subsonic flow at the nozzle with a mach of 0.59. but the Pressure-farfield BC sets the entire domain to a mach, i am not sure about that.
