Syntax

Bc Lumped_Flux For Energy ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = Ray_Trace [Using Data Specification Data Spec Name] ([Power_Output = power_output] | [Flux_Output = flux_output] | [Toggle = toggle] | Ray_Source = ray_source | [Emission = emission])

Summary

Apply a ray tracing energy flux

Description

Adds an energy flux based on the intersection of rays defined in a ray tracing source block for the equation system with name given by the RAY_SOURCE parameter with the surface. The optional EMISSION parameter also imposes a \sigma T^4 blackbody radiative emission term

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.
