24 Class
25  Foam::radiationModels::P1
26 
27 Description
28  Works well for combustion applications where optical thickness, tau is
29  large, i.e. tau = a*L > 3 (L = distance between objects)
30 
31  Assumes
32  - all surfaces are diffuse
33  - tends to over predict radiative fluxes from sources/sinks
