Hi all,

can anyone explain me the difference between the quantity "incident radiation" (unit W/m2, under Radiation...) and "surface incident radiation" (also W/m2, under Wall fluxes...)?

Thanks in advance

Hi philus

I had the same query.. Did you find the answer ?

Thanks

I had found an empirical answer to that and was something like:

the wall fluxes->incident radiation is the radiating energy flux incident to the surface, while the radiation->incident radiation is the sum of all radiation (incident, transmitted and reflected) on both sides of the selected CELL.

But it is still foggy for me I'm sorry..

Yes i figured out that the one under wall fluxes is the one i require.

Incident radiation can be computed/visualized at any arbitrary location (a point placed anywhere in the domain).

Surface incident radiation under wall fluxes is limited strictly to walls.

It's similar to a local heat flux vs the wall heat flux.

I find the incident radiation on the wall is different from sureface incident radiation.
