FunctionRadiativeBC
Boundary condition for radiative heat exchange where the emissivity function is supplied by a Function.
This boundary condition computes the radiative heat flux from a boundary where the emissivity function is provided through a Function.
where is the Stephan-Boltzmann constant, is the emissivity function, is the temperature far from the surface, and is the temperature of the surface.
