Hello,

I am analzying following case in Fluent.
-> 3D
-> Transient
-> Mass flow inlet BC (Transient Mass flow, Always positive)
-> Pressure Outlet BC (Static Pressure = 0 Pa)

With the above setup, when i monitor the static pressure at the inlet, i am getting negative static pressure at inlet.
Thus there is a negative pressure at inlet and 0 Pa at outlet. Technically, there should be a reverse flow, but Fluent shows no reverse flow.

Also, as my inlet mass flow bc always applies postive value for mass flow rate, static pressure at the inlet should always be higher than the outlet pressure, shouldn't it?. But i am getting it completely opposite.

Any comments why this is happening?
