Computing View Factor

Hello, I have performed simulations of surface-to-surface radiation using solar and ambient settings to account for the wavelength dependence of the radiative properties. I would like to verify the view factor between two surfaces. I have already obtained great information from this: https://www.comsol.com/blogs/computing-view-factors-with-the-heat-transfer-module, being able to verify the view factors for the constant wavelength dependence of the radiative properties using the rad.radopd and rad.radopu operators. I tried to do the same using the operators rad.radopB1u or rad.radopB2u but always got an unknown operator error message. I have also tried using a different syntax based on the definition of other variables within COMSOL getting the same result. I thank in advance anyone who can help me solve this problem.
Many thanks and kindest,
Aniello

Hello Aniello,
The names of these operators have changed since that was written, they are: rad.radopu1(Ju, Jd) rad.radopd1(Ju, Jd) rad.radopu2(Ju, Jd) rad.radopd2(Ju, Jd)
