i calculated the ratio (radiative heat flux/total heat flux) along a line of the wall. i am getting values greater than 1. i cannot understand this. please help me.

ASAIK, the total heat flux in FLUENT is the sum of the convective and radiative flux contributions, qr and qc, each of which may be positive or negative. Thus if, for example, qr=-qc, you'll get infinity (>1 ...).
