[Carlo_P]

Hey guys,
I'm trying to simulate the flow in a T-Pipe, with two Inlet (upper and left) and 1 Outlet.


In the Inlet_up flows a fixed massFlowRate
In the Inlet_sx the flow is coming inside due to a difference of pressure
In the Outlet, the flow is going out.


I have some problems in the BC, in particolar in the Inlet_sx.
I'm not sure if is better to use TotalPressure or fixed value for p and pressureInletOutletVelocity for U.



In the Inlet_up: U=massFlowRate
p=zeroGradient


In the Outlet: U= zeroGrazdient
p= fixed value0


In the Inlet_sx:
U= zeroGradient or pressureInletOutletVelocity?
p=totalPressure or fixedValue?



Thanks for any suggestion!
