I changed the gravity now to +9.81 m/s²


The result is the same. The liquid flows upwards outside of the screw.


It is correct, that the liquid is being squeezed through the holes of the screw, as you can see in the following picture.


But I don't understand why it flows upwards after that. In reality it flows a bit upwards as well, because of the pressure that squeezes the liquid out of the holes, but not that much. Most of the liquid must flow downwards because of the gravity.
