Are there any tutorials for radiative heat transfer simulations in OptiStruct?

I'm currently working in Hypermesh/OptiStruct 2022.3 and trying to run a radiative heat transfer simulation for the first time. I've been looking into the user guide and am still lost on how to implement many of the required inputs. For example, it says to add the Stefan-Boltzmann constant through "PARAM, SIGMA" but I don't see this option anywhere in the control card PARAM. Same for "PARAM, TABS" for defining absolute temperature. 

There are other inputs, such as RADBC, RADM, CHBDYE elements, black body space node, etc. that I can't figure out how to implement. I think I understand the general theory being applied from following the user guide, but not how to actually implement these into an analysis. 

Also, when I switch the User Profile to NASTRAN I see the options for TABS & SIGMA, but when I go back to OptiStruct/Hypermesh I no longer see them (so I assume I'm looking in the correct location). Could I possibly be missing some file downloads for software capability?
