This widget allows to activate the confined radiation option. A new group of windows then appears in the left part of the window.

This thermal radiation functionnality is relative to wall to wall (transparent medium between the walls) radiation in complex enclosure, with possibly shadowing effect. It is based on a radiosity approach, in which view factors are calculated during an initial step. It cannot handle so far radiation within participating media, even if SYRTHES authors are thinking to handle radiation within these kind media in the future.

If only a "simple" radiation boundary condition is required,then use the window Conduction/boundary conditions/Infinite radiation to set the adequate parameters.

Radiation is automatically coupled with conduction within SYRTHES. It has no meaning to activate radiation without activating either conduction or Humidity models.
