Hi guys,

I'm trying to predict the acoustic noise generated from a four bladed helicopter rotor. I'm using rigid motion for the rotor's rotation and morphing motion for blade pitching motion. I'm using the On-the-fly FW-H solver to predict the acoustic noise but I it isn't working. I get the message;
"FW-H Surface: Impermeable surface 1 has boundary: blade 1 with no stationary or rigid motion"
"On-the-Fly FW-H model is only available for stationary and rigid motion"

I would be most greatful for any help in solving this problem.
