I want to give boundary condition for wall as :: reradiating and adiabatic

meaning i dont want to give q=0 that will make convection+radiation heat tranfer=0 which i dont want

thanx

by the way i hope i have understood meaning of external radiation somewhat like the cases such as- radiation is coming to earth from about 5k or in a tall enclosure temp of the walls concerned for analysis on ground is that so ?? thanks for the reply
