Hello all. Here are my BC for the fire source.
for U:
"fire.*"
{

type flowRateInletVelocity;
massFlowRate table
(

( 0 0 )
(100 0.01)
(150 0.03)
..................
.................
);

rho rho;
rhoInlet 1.0;
}

for P and p_rgh:
"fire.*"
{

type fixedFluxPressure;
phiHbyA phiHbyA;
phi phi;
rho rho;
Dp Dp;
}

Solver - firefoam. Mass fraction of the fuel at "fire" is 1.0. HRR of the fuel is 9.0e6 J/kg. But the total HRR can not be estimated. It extremly depends on mesh resolution and square of fire surface. I tried different BC for the pressure but did not find out needed one. I would like to have stable HRR at different sizes of the mesh cells. Please help with resolving this problem. Thanks.
