Hi

I have a little question with the buoyantBoussinesqSimplefoam solver. I run a simulation for a room with supply and extract system air. But It works only when supply flow=extract flow otherwise I have continuity error message. I would like to know if we can simulate an overpressure room even if buoyantBoussinesq is for incompressible flow. I would like to know if it possible without using potentialfoam.

I have for p
zeroGradient ( supply qnd extract)
for U
flowRateInletVelocity ( supply)
flowRateOutletVelocity ( extract)
for p-rgh
fixedFluxPressure
uniform 0 (supply and extract )

Thanks a lot

Have a nice day
