doubt on defining continuum type
 

Hi, I'm modelling an axi-symmetric combustion problem. I divided my entire domain into 4 faces and meshed it. I then selected FLUID type for all four faces. While reading the case in FLUENT, it is not showing individual FLUID type that I have created in GAMBIT. Should we define any boundary condition to the line that forms the interface between the FLUID zones? Can anyone let me know their suggestions Thankyou
