Fast S-function parameters v7

Good afternoon,

I am a new user of FAST. First, I have used FAST v8 for my simulation and it was working. However, in order to apply my control system I need the linearization module. So, I have uploaded FAST v7.
But, with this version, I have a problem with the S-function parameters. I do not know how to choose them.
I have compared with the parameters of v8 which are: FAST_InputFileName, TMax, 0
So I have tried with : input_fast (the similar parameter of FAST_InputFileName), TMax, 0
But it is not working. I think that I need 3 parameters. But which ones?

Thank you in advance for your answer.

Dear Audrey,

I’m not sure I fully understand your question, but the Simulink interface for FAST v7 is well documented in the old FAST User’s Guide: nwtc.nrel.gov/system/files/FAST.pdf (see the section titled, “Simulink Interface”). I suggest that you start there.

Best regards,

Dear Jason,

Thank you for your prompt answer. I have solved this problem but I have another issue by running the simulations.
I have explained the problem by posting a reply in another and more relevant topic:
