Description
Fixed heat boundary condition to specify temperature gradient. Input
heat source either specified in terms of an absolute power [W], or as a
flux [W/m2].
Example usage:
hotWall
{
type compressible::turbulentHeatFluxTemperature;
heatSource flux; // power [W]; flux [W/m2]
q uniform 10; // heat power or flux
kappa fluidThermo; // calculate kappa=alphaEff*thermo.Cp
Qr none; // name of the radiative flux
Description
Incompressible gas equation of state using a constant reference pressure in
the perfect gas equation of state rather than the local pressure so that the
density only varies with temperature and composition.

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
