Hi everybody,

I'm looking for a way to impose the total pressure as inlet boundary condition, instead than a velocity.

My solver is a incompresible flow, and I try the followings conditions for inlet:

1) TotalPressure for p, pressureInletOutletVelocity for U
2) TotalPressure for p, fixedValue for U

I used the utility "calcMassFlow" for calculate the flow in the patchs, and for 1) in inlet patch , the flowrate increases and 2) the flowrate is constant. Why is that the variation in the mass flow in the two options?

Regards
