We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

See thats just it. The time step size is not changing the result as if it did, I would have seen atleast an infinitesimal movement. But the flow is reversed. I even tried to modify the boundary conditions for the fluid making a pressure inlet and a pressure outlet and setting the gauge pressures to 0 for the initialisation before performing DPM. But this does not change anything.
Till now, I do not understand what exactly went wrong with the physics, as it seems pretty accurate in my eyes
