Hi Chaitanya,

Thank you for the explanation, I have a beter understanding now. Just to clarify, if the scattering fraction is changed to 0, this means none of the rays at the BC walls will be reflected and this energy will remain absorbed by the BC? 

It does seems like the issue is that the solar ray tracing is only capturing the effects up until Body 3 (the first opaque surface) of my model. As I am interested in changing the solar properties (such as absorptivity) of body 6 (which is also an opaque wall), this method of analyzing may not be appropriate. On top of the solar ray tracing, would incorporating  another models, such as a DO model, be more appropriate for this problem? 

Thank you again,
