That is, minuscule values. I have a tube with a total pressure defined at one end and a heat flux. Question is, am I leaving some reference density out?
Namely, this rhok, found in the boundary/initial conditions for p_rgh:

VOL1FACE3
{
type buoyantPressure;
rho rhok;
value uniform 0;
}

it's not defined anywhere else in my case.

hi Tushar, I figured out what the problem was, I had the BCs for p and p_rgh switched.
