Hi Jason,
I’m working with the OpenFAST 1.5 MW wind turbine model and would like to feed in user-defined wind input data. Currently, I have wind measurements defined as wind speed at 80 m and wind direction.
When I run the simulation and compare the logged wind velocities to inputs generated from TurbSim, I notice considerable differences. Could you please advise which parameters I should adjust to ensure that the simulation wind field better matches the user-defined input?
Thank you for your guidance.
Dear @Mohammed.Alabsi,
Presumably you are using TurbSim’s TurbModel = TIMESR functionality. Can you share your TurbSim primary and UserFile input files and clarify what in the output is not matching what you expect?
Best regards,
Thanks for getting back to me. Here are the screenshots. My expectation was that the TurbSim output fed into OpenFAST would match the logged wind speed after running the simulation.
Dear @Mohammed.Alabsi,
I’m not sure how TurbSim is interpreting this, but your TurbSim UserFile does not seem to be formatted properly. Your file indicates nPoints = 5 with nComp = 3, but this would require 5 rows of (Pointyi, Pointzi) coordinates and 5*3+1 = 16 columns of time series data, which you have not specified.
Best regards,
