= 0 → exchange between 2 faces belonging to the same structure (CONRA element)
= 1 → Radiation towards a fictive surface (leak flow or symmetry)
= 2 → Radiation between a face representing the symmetry and a face representing a leak flow

Results

  • Sigma(1): flow unaffected by the viewing factor
  • Sigma(2): flow affected by the viewing factor and the area of the element ($A_1 F_{12}=A_2 F_{21}$)
