This node can be added to pairs. When the Radiation discretization method is
Discrete ordinates method, it prescribes that the radiative intensity field
I is continuous across the pair. When the
Radiation discretization method is
P1 approximation, it prescribes that the incident radiation field
G is continuous across the pair.
Continuity is only suitable for pairs where the boundaries match.
The Constraint settings can be set to
Pointwise constraints (default) or
Weak constraints. Select
Weak constraints to replace the standard constraints with a weak implementation.
