Hello sir,
In conjugate heat transfer problem i am using monte carlo (MC) radiation model.

For solid (Brick wall) domain i have selected
Thermal radiation -monte carlo
number of histories - 10000
Transfer mode - surface to surface
spectral model - Gray
Scattering model - none

For fluid(AIR) domain not selected any radiation model because air is transparent
to radiation.is this approach correct or i have to select radiation model for air domain also.and sir in CFX is it radiation depends on number of elements.
Thank you sir,
