Dear Jason,
Thank you for your quick and detailed reply, I really appreciate it!
You make a good point about the two joints close to (0,0,-30). I think that is exactly what is appearing in my HydroDyn Input file, and these values were originally here when I downloaded the files from GitHub. Please see attached image. Bearing in mind this is the 15MW turbine, can you please suggest appropriate values for me to insert for Jointxi , Jointyi , Jointzi ? Thank you kindly.
Best regards,
Matthew
