Dear Long,
The MATLAB scripts used to read the TurbSim output and plot these figures are included in the forum posts in this topic above.
Best regards,
Dear mr. Jonkman
Hello and sorry to bother you again. I am now trying to run a longer simulation (300sec) and I need to produce my own wind field with TurbSim. I downloaded the library from Github “GitHub - old-NWTC/TurbSim: A stochastic, full-field, turbulence simulator”. And I try to run TurbSim through windows command prompt as I do with FAST. It is bothering me that it doesn’t have the ending “.exe” like the FAST does but the ending “f90” . When I try to run it I get the message:“‘TurbSim’ is not recognized as an internal or external command,operable program or batch file.” Is there any case that the turbsim file is broken? Or am I doing something wrong??
Thank you a lot in advance
Dear Manolis,
The *.f90 file is the source code; you must compile this version of TurbSim before running a simulation. The compiled version should have a *.exe extension on Windows.
You can find an archive of TurbSim v2.00.07a-bjj on my Google drive that contains the TurbSim source code, documentation, sample models, CertTest, and precompiled Windows executable here: drive.google.com/file/d/1eCvgoO … sp=sharing.
Best regards,
Dear mr. Jonkman
Thank you very much for your help. I managed to produce my own wind field.
Have a very good day
Dear Jason,
I’m working with IEA 15MW FOWT model using OpenFAST, the question is the input file of TurbSim_x64.exe from GitHub link gives these values for wind modeling:
The maximum chordlength of the rotor blade is 5.77 m for IEA15MW WT, so I’m confused about these values in the input file. What do you think of this?
According to what you said above, I tried to define the values of these parameters myself, as follows, can you please have a look and tell me if it is reasonable for IEA 15MW FOWT?
Thank you in advance.
Best regards,
Lei
I’m sorry I tried these setting but it failed to run, could you please have a look about this error?
Best regards,
Lei
Dear @Lei.Xue.
Example models provided by NREL don’t always follow the modeling guidance, e.g., with a model often provided coarser than recommend to minimize computational expense or file size for testing purposes.
For very large wind turbines it is often difficult to follow the modeling guidance exactly, like maximum chord being the recommended spatial discretization for turbulent inflow. For the IEA Wind 15-MW reference wind turbine, it is likely sufficient to use a bit larger grid spacing (perhaps from 5.77 to 7-10 m) and also to increase the TimeStep (perhaps from 0.05 to 0.1 s) given the natural frequencies and rotor speeds are lower for this very large rotor than when the modeling guidance was first developed.
You can always perform your own convergence study to assess sensitivity of the results to spatial-temporal resolution for the simulations you have in mind.
Best regards,
Thank you for your answer. I really appreciate your timely reply.
Best regards,
