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.

Hi Rob,

Thank you very much for your message.

I tried without UDFs and only with named expressions. Instead of applying UDFs (input and output) to the rear airfoil, I used a named expression (same as for the front airfoil) as an input for it to pitch. It worked well.

When I tried to debug the issue, I noticed that while compiling the UDFs (using the in-built compiler), those were not updated in the directory ("libudf" and "libudf2" folders). While compiling, sometimes (not always) the console shows a message "Access is denied" to the directory.

Could you please help me with this?

Regards,

Muhammed Sadique
