BCs - Radiation - Radiation to Ambient:

Please refer to the main Boundary Conditions page for an explanation of the standard components of the boundary condition forms.

 
Plane: Radiation to Ambient can either be associated to surfaces (Associated to Geometry) or to a 2-D planar region (Specified Region).
Ambient Temperature (Tamb): Radiation to ambient requires the user to specify ambient temperature which can be a constant or variable and the surface emissivity value.
ViewFactor (ViewF): The user needs to supply a view factor( geometric shape factor) which can be a constant or variable.
