Nevermind, your comment was funny and not patronizing.

Basically, I wouldn't need a time factor if I can set the volume flow rate to be constant along time rather than the mass flow rate. I'll...

I may have poorly explained what I meant:

Let's say my outlet BC is mass flow rate = 1

At t=0 I may have
mass flow rate = 1
volume flow rate = 1
rho = 1

At t=1, rho changes because...

I am using compressible flow with the solver buoyantPimpleFoam but I know the volumetric flow rate of my extracting system so I'd like to use it.

I'd like to work with constant volumetric...

"The basis of the patch (volumetric or mass) is determined by the dimensions of the flux, phi."

Do you know where I can find the dimension of phi?
