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.

With a very small particle time step you're adding droplets at a very high frequency, which may explain the high count. Depending on the injection angle you're also potentially adding them into the flow boundary layer - do they have sufficient momentum to penetrate the flow domain? Why 50,000 integration steps? Shed implies you're also running a wall film model?Â
