Hello Ananya,n1- You can do that in multiple ways:nA-You can use mixed bc where you can specify the radiation at the bc.nB-You could apply a heat flux at the boundary directly.nC-You can use Solar radiation model to consider radiation from outer sources.n2- I am not completely sure what you mean but I guess you are talking about gas absorption and scattering. They are considered in steady as well as transient simulation and can be specified in the material panel.nBest Regards,nJohnn
