24 Class
25  Foam::buoyantPressureFvPatchScalarField
26 
27 Description
28  Set the pressure gradient boundary condition appropriately for buoyant flow.
29 
30  If the variable name is "pd" assume it is p - rho*g.h and set the gradient
31  appropriately. Otherwise assume the variable is the static pressure.
