Hi every one
The following boundary condition of turbulence is given in fireFOAM-dev without physical discription.

alphat - thermal diffusivity
type alphatFirewallFunction;
Qc 20000;
QcThreshold 2000;

nut - eddy diffusivity
type nutFirewallFunction;
QcFlame 20000;
QcThreshold 2000;

where
constant/QcWallfunctionDict has
QcFlame 20000;
QcThreshold 2000;

I could not understand the option meaning QcFlame and QcThreshold and values ?? what is physical meaning of this options.
