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.

Reverse flow isn't an error, it's a warning. Given the flow is probably more-or-less aligned with the boundary there's a good chance the mass of back flow is fairly low: have a look at the velocity vector plots. Also, have a look at the backflow options in the panel (hint, preventing backflow needs to be used with caution, so don't just look at that).Â
