When using a 'thermal condition' in static structural analysis, isn't radiation considered? If not, could the resulting stresses be inaccurate due to the neglect of radiative heat transfer?

Hi
Static structural has only UX, UY, UZ degrees of freedom and not temperatures.
Thermal condition imposes temperatures (temp.) as a load/boundary condition that then cause thermal strains (alpha * DT). Now if the temp. is not the same everywhere we can do a thermal analysis to find out what it is.So if one wants we can do a detailed thermal analysis including radiation, to find out the temperature distribution, and then transfer these temperatures to the static system for a thermal stress analysis.
See here on how to do this (thermal - > structural analysis):
