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.

If you're using the open channel the downstream flow will alter the inlet mass flow. How does the free surface look? Is there a hydraulic jump?  I know why profiles are used, but it's sometimes better to just accept the compute overhead and model the whole lot in one go.Â
