libopenfastlib.dll Function

[wkdanqu1]

Hello Professors,

I found this subroutine 'FAST_SetExternalInputs' in FAST_Library.f90. Could I use this subroutine to change specified input parameters in ServoDyn at each time step?

If the above method is feasible, could I also use it to modify input parameters for AeroDyn at each time step?

Thank you for your help,
Best Regards,
Jesse

Dear @wkdanqu1,

SUBROUTINE FAST_SetExternalInputs() of FAST_Library.f90 is used to transfer inputs to the OpenFAST S-Function from Simulink to ServoDyn. These data (generator torque, blade pitch, etc.) are normally outputs calculated within ServoDyn, but this routine allows these data to be calculated within Simulink.

I'm not sure what AeroDyn "input parameters" are you referring to, but a source code change would be required if you wanted Simulink to calculate other variables normally set within OpenFAST.

Best regards,
