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 report the force on the airfoil wall (print the return for force[1] ) for some timesteps but use the second block of commands in the UDF what sort of numbers are you seeing relative to what you expect? Also, I can't see a mass in the system - what stops the wing just accelerating upwards?Â
