# Enclosure_Radiation

Syntax

  Bc Diffuse For Energy ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = Enclosure_Radiation [Using Data Specification Data Spec Name] ([Power_Output = power_output] | [Flux_Output = flux_output] | [Toggle = toggle] | [Multiplier = multiplier] | Enclosure = enclosure)

Summary

  This term imposes an energy flux due to enclosure radiation as defined in Enclosure Radiation. The irradiation is provided by the Chapparal radiosity solution

Description

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

  Power_Output

    If specified, the total (integrated) power of the given BC/Src is calculated and stored into the global variable name specified as the power_output argument.

  Flux_Output

    If specified, the average flux of the given BC/Src is calculated and stored into the global variable name specified as the flux_output argument.

  Toggle

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