Rad

Syntax

Bc Flux For Enthalpy ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = Rad ([Toggle = toggle] | Crad = crad | T_Ref = t_ref)

Summary

Radiative energy flux defined with constant models for emissivity and reference temperature.

Description

The applied flux is given by:

c_{rad}\left( T^4 - T_{ref}^4 \right)

The following options are present in most boundary conditions/sources. The meaning of each option is as follows:

Toggle

If given, specifies which toggle block controls whether this BC is active or not.
