Reply To: Fluid flows upwards despite the fact that gravity is enabled

Just a quick comment. You need to have your acceleration as +9.81m/s2 in the X dirextion otherwise your gravitational acceleration is wrong.
From the picture you posted it seems the flow is reaching a wall and being squeezed upward or seeping through a hole. You need to check your geometery and mesh for any anomalies.
