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.
