Error in running TurbSim

Wind & Water Wind Farm Modeling

Dear Mohd,

My answer is “yes” to both of your questions. The user-specified options in TurbSim make it completely tailorable to your own mean profile, turbulence spectra, etc.

Best regards,

Hello Dr. Jonkman,

I am trying to generate formatted full-field files (.u, .v and .w) for TIMESR case. The code is running but the these files are not generating with below error in the command window (Capture.PNG).

Could you please let me know where the problem is as I could not figure out?

23

The error you are showing indicates a problem in the source code. I would first check if the TurbSim executable from OpenFAST has the same issue (you can download a pre-compiled binary here: github.com/OpenFAST/openfast/issues.

hi
I have tried several times to generate wind data with both turbsim v1.5 and turbsim v2 but I get the following error

Dear @Ali.Rouhbakhsh,

Your input file is formatted for TurbSim v1.5, but you are running TurbSim v2.0. You must upgrade your input file for compatibility, including adding the following lines:

Line 4, Echo
Line 32, UserFile
Line 38, ProfileFile
Lines 53-57 for a blank line, header, and inputs SCMod1, SCMod2, and SCMod3

See the TurbSim v2.0 documentation and sample models for more information: TurbSim | Wind Research | NREL.

Best regards,

26

I did what you said, but I think the problem is that I set the IECstandard parameter “2-ed2” in the software input, which causes an error, but when I set this parameter to something else like “1-ed3”, the software runs correctly

So what do you think I should do to solve this problem?

29

If you want to use IEC 61400-2 default scaling, enter 2 for the IECStandard input. The optional edition number for that parameter is only for the -1 standard. 2-Ed2 is not a valid entry.

Dear Sir,

I downloaded TurbSim_v2.00.07a-bjj.exe this file from https://www.nrel.gov/wind/nwtc/turbsim.html. For running this file I need TurbSim.inp file. From where I download this file?

31

There are sample input files in the self-extracting archive that you’ve already downloaded (double-click that TurbSim_v2.00.07a-bjj.exe file, and it will extract the files, including the TurbSim executable, documentation, and sample input files).

32

Thanks for your reply. Finally I know to run (syntax in cmd) TurbSim file using TurbSim.inp file.

How I run AeroDyn file after downloading r-test-main file? Which file is necessary to run this? What is the syntax in cmd?

Thankyou

33

Dear @Aman.Ali,

I’ve answered the similar question you posted in the separate forum topic regarding how to run TurbSim and AeroDyn (How to run TurbSim and AeroDyn?).

After compiling the standalone AeroDyn driver, the input file you need to specify when executing the simulation is the AeroDyn driver input file, as documented here: 4.2.1.5. AeroDyn Driver — OpenFAST v3.3.0 documentation.

Best regards,
