Generalized_Rad

Syntax

Bc Bulknode_Flux For Energy ([{of} SpeciesName] | [{in} MaterialPhaseName] | [{ls} {a | b | c}]) {@ | at | for | on | over} Mesh Extent Name ([Touching TouchingMeshExtent] | [Opposing OpposingMeshExtent]) = Generalized_Rad [Using Data Specification Data Spec Name] (Bulk_Node = bulk_node | [Multiplier = multiplier] | [Toggle = toggle])

Summary

Applies a heat flux of the form J \cdot n = \sigma \epsilon F (T^4 - T_{bulk}^4) where \epsilon is the emissivity defined in the solid material model and F is the radiation form factor defined in the surface material (optional, defaults to 1).

Description

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.
