Hi, As the title suggests I am trying to model a beam incident on (a small portion of) an absorbing-scattering media. The problem is I can see 2 possible routes to achieve this but neither really works: 1- Beam in absorbing media: easier solution and the results look credible but I don't think its possible to add the scattering effects, which are pretty significant in my problem and therefore can not be neglected. 2- Use radiation in absorbing-scattering media: Unfortunately something is wrong here I don't completely get it. I can't find any transparent boundaries here and thats probably why the incident intensity values I set in the boundary conditions are not the same as the ones I get in the results. Thanks.

I just noticed that the same thing is happening in the Light Diffusion in a Slab of Particles sample problem. the incident radiation intensity boundary condition is set as 557.98 W/m² W/m^2 but the results show a maximum incident intensity of 6000. I would appreciate if someone explains why this happens.
