Yaw error ,HorWndDir in FAST 8

[Sepideh.kianbakht]

Hello,

For implementing Yaw control in Simulink I need Yaw error and HorWndDir, but it seems that they have been removed from the FAST8.Woud you please guide me how I can get Yaw error from Outlist of FAST8 ?

Regard,

Dear Sepideh,

While these two outputs have been eliminated from FAST v8, it is not difficult to calculate them from the available outputs. For example, the horizontal wind direction can be derived from the X and Y components of the wind vector outputs available from the InflowWind module and the nacelle-yaw angle may be output from the ElastoDyn module.

Best regards,

Thank you.
