Hi all,

i'm again not sure of my understanding and trying to clarify.

I've got a real situation where in a domain thats somewhat of a tube with one inlet and one outlet exists. I know the ingoing mass flow and at the outlet a manometer shows the static pressure (in my understanding).

for buoyant Solvers i can only specify the absolute pressure or the dynamic pressure, but my only information concerns the static pressure. so how can i set my pressure boundary?

For my inlet i will set a flowRateInletVelocity and a zeroGradient pressure. At the outlet i will set fixedFluxPressure and i have to specify the pressure here.
