If the check-box indicating that the radiation mesh is
not forming a closed domain has been checked,
the temperature (in degre C)
of the exterior has to be specified in that field.
In that situation, one notices that
the external domain behaves as
a black body (emissivity of 1 can be specified)
If possible authors suggest to use preferably the imposed temperature
functionality. It has the drawback to oblige users to mesh explicitely
the opening but then the general algorithms
are used ensuring conservativity at the radiation level
and an emissivity different from 1 can be specified and can vary from
one region of the opening to another.
