Description🔗

The MarshakRadiationFixedTemperature is a mixed boundary condition that provides a Marshak condition for the incident radiation field (usually written as G).

The radiation temperature field across the patch is supplied by the user using the Trad entry.

Usage🔗

The condition requires entries in both the boundary and field files.
