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
