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.

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.
