Default max residual I-radiation (Discrete Transfer)

hi,

I am modelling radiation heat transfer in non-boyant fluid media (absorption coefficient 50 m^-1) using Discrete Transfer model. Fluid is in a closed volume; temperature boundary conditions on the faces (emmisivity 0.9). H-energy converges well; the problem is - I do not see I-radiation residual at all - even if I change the range to (1e-100; 1e+100). I can see only the legend of I-radiation, but there is no line in the plot. The only residual I can plot (concerning radiation HT) is I-Radiation domain source.

Where can be a problem? thank you in advance

probably, found the problem by myself - Discrete Transfer model is not appropriate for absorption coefficient 50 m^-1.
