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.

Are you using constant density for the water or the compressible fluid formulation? I would suggest first that you use compressible fluid to see if this reduces any potential pressure spikes which may contribute to this floating point error. If that doesn't help, then you should consider using remeshing.
