FAST S-function

Hello,

I am trying to run the Simulink examples in the FAST archive in Matlab/Simulink R2007b. I am using the FAST files from this topic: [forums.nrel.gov/t/fast-s-func-mexing-process/143/1)

After following the procedure is FAST.pdf, I am still unable to run the Simulink files. Below are the errors from Simulink and Console.txt. The files shown below in Console.txt do not exist in Wind/AWT27/ folder. Please let me know if I am missing anything simple.

Thanks,
Bhaskara

Check your AeroDyn input for proper wind file name.

Dear Bhaskara,

The error you are getting is from AeroDyn and is saying that it can’t find the wind file Shr12_30.wnd. This file should be stored in the Wind/AWT27 directory of FAST’s CertTest folder. Is it? It sounds like a path has been changed somewhere. Are you running the simulation from the CertTest folder? If not, have you copied all of the model files (including the wind file) to the folder where you are running the model from?

Best regards,
