Description
|
||
|
View factors are calculated based on a face agglomeration array
|
||
|
(finalAgglom generated by faceAgglomerate utility).
|
||
|
|
||
|
Each view factor between the agglomerated faces i and j (Fij) is calculated
|
||
|
using a double integral of the sub-areas composing the agglomaration.
|
||
|
|
||
|
The patches involved in the view factor calculation are taken from the Qr
|
||
|
volScalarField (radiative flux) when is greyDiffusiveRadiationViewFactor
|
||
|
otherwise they are not included.
