Does ROSCO 2.4.1 not work with .bts type wind files?

[SYZ622]

When I run ROSCO again after changing the wind file to .bts, I get the following error Error reported by S-function 'FAST_SFunc' in 'ROSCO1/FAST Nonlinear Wind Turbine/S-Function': FAST_Solution:FAST_AdvanceStates:SolveOption2c_Inp2AD_SrvD:InflowWind_CalcOutput:CalcOutput:IfW_FFWind_CalcOutput [position=(NaN, NaN, NaN) in wind-file coordinates]: Error: FF wind array was exhausted at 0.575 seconds (trying to access data at NaN seconds).

ROSCO does not read .bts files. OpenFAST does. I suspect there is an issue with your model or controller that causes those NaNs. Without more information, it's difficult to help you.

The Test_Cases that come with ROSCO use steady wind, but after I changed the incoming wind input file in Openfast to a wind file generated by Turbsim, I got the above error. Also, I would like to ask how to determine the version of ROSCO and the corresponding version of Openfast?

They can be found in the print statements when OpenFAST and ROSCO are run. Or if you installed via conda, you can conda list | grep openfast or | grep rosco.

I suspect there may be an issue with your bts file if it runs okay in a steady wind.
