Hello,
i want use buoyantBoussinesqPimpleFoam.
1-in B.C of pressure what is this mean? :

Code:
        type            buoyantPressure;
        rho             rhok;
        value           uniform 0;
2-is it same as incompressible solvers like pipmpleFoam with temperature field?
i mean can we use it for ventilation of a room with inlet mass and outlet or we should use another solver.
Best,

Hi,
I use buoyantBoussinesqPimpleFoam too.
My boundary condition for pressure (p_rgh) is:
Quote:
type totalPressure;
p0 uniform 0;
U U;
phi phi;
rho rhok;
psi none;
gamma 1;
value uniform 0;
Because there is no rho in the solver, so I have to use rhok instead. But I am not sure if it is OK. I'm expecting someone could explain the details about this rhok. Thanks!
