Fluent radiation model
 

I am trying to currently recreate a fluent office room model with surface wall, panel radiation. In another paper the researcher did the same CFD model in phoenics and use an IMMERSOL radiation model. In fluent which radiation model should i be utilizing as i am trying to take into account convection and radiation by radiant cooling panels and the wall surfaces. i was thinking it should be P1 as rossaland doesnt take into account wall emmissivity.
