Hello everyone,

I am working on a Projekt where I have a surface to surface radiation. If I give one surface an emissivity lower than 1, these factors are not taken into account for Walls and shadow-walls (boundary conditions). Even if I put in 0 as emissivity, there is still a radiation heat flux going on.

Hello Matthias, nWhich version are you using? nPlease try using the TUI command, /define/boundary-conditions. Select the surface and set the value of internal emissivity there. However, the value of internal emissivity might not show up in the GUI. n
