Surface incident radiation
i'm using in my simulations a semitransparent wall which is passed through by a radiation fixed by me, and in front of the semitransparent wall, I have another wall which receive the radiation.
When i set the radiation for example in 750 W/m2 , the other wall receives 700 W/m2 as the surface incident radiation reports (it's okay because of the reflected radiation and the others boundaries). But when I use for example 100 W/m2, the other wall receives 300W/m2, so that it's impossible, and i don't know why. If i use the other wall fluxes (total heat flux, radiation...) all it's okay, but i need to know the surface incident and the absortion radiation in my wall for my results.

I'm using OD model and in my semitransparent wall, i defined the option mixed (radiation and convection)

PD: sorry for my english
