Dear all:
I have a problem when running TurbSum. When I type the syntax in command promote as the instruction of TurbSim, it shows an error like:
C:>Users\s1707212\Downloads\TurbSim\TurbSim64.exe CertTest.inp
Using NWTC Subroutine Library (v1.04.01, 21-Feb-2012).
Running TurbSim (v1.06.00, 21-Sep-2012).
Cannot open file “CertTest.sum”. Another program like MS Excel may have locked it for writing.
Aborting TurbSim.
Could you please help with this? Thank you very much.
Dear Yajun.Ren,
It looks like you are running a model called CertTest.inp that is stored in C:; is that correct? Do you have a file named CertTest.sum already located there?
Best regards,
Hi

Dear Vahid,
A similar question was asked and answered in my post dated May 19, 2015 in the following forum topic: Compiling Turbsim - #9 by Jason.Jonkman.

Dear Jason,
Thanks a lot for your attention,

Hi,
Could I know where can I download the latest version of Turbsim?
I have downloaded a zip folder called Turbsim-master where I cant find any certtest.inp.
Thanks,
Satish J.
Dear Satish,
TurbSim v2.0 is available on my Google Drive: drive.google.com/drive/folders/ … sp=sharing. And there is a slightly newer version of Turbim, based on v2.0, included in the OpenFAST repository in github.
Best regards,
Dear Jason,
Thanks for your reply.
I will check this one, thanks!
Thanks,
Satish J
Dear Jason,
I am getting following error when I run the Turbsim and I have attached input file. Could you please advice me on this?

Dear Satish,
It looks like your TurbSim input file is compatible with TurbSim v1.50, but TurbSim within OpenFAST is based on TurbSim v2.00. You can find the TurbSim v2.00 archive, with appropriately formatted input files, here: drive.google.com/file/d/1eCvgoO … sp=sharing.
Best regards,
Dear Jason,
Thanks for your reply.
I edited my turbsim input according to v2.00 and I got the output, thanks!
Thanks,

Dear jason
when i run TurbSim v1.50 i get the followng error. The only thing i changed in the input file is uref
how can i fix this?
best regards
georgia
Dear Georgia,
Are you saying you run TurbSim v1.50 and it runs as expected, change Uref in the TurbSim input and run again and get this error? This doesn’t really make sense to me. Sharing your TurbSim input file may help me understand.
Best regards,
Dear Jason
i got this error before changing uref . I havent run turbSim successfully
should i change the location of turbsim?
this is the last input file i used
thank you

Dear Georgia,
OK, that makes more sense. You are getting this error because you’ve set WrACT = True, which requires that you have the coherent structure data files stored on your computer, located in the directory indicated by CTEventPath. I suspect that you don’t actually want to use the coherent structures, so, set WrACT = False and the error should disappear.
Best regards,
Dear Jason,
thank you! my problem is solved

Georgia
Hello Dr. Jonkman,
However, when I am writing the command from my windows prompt it says ; “TurbSim not recognised as an internal or external command, operable program or batch file.” I have changed the path as per Marshall’s document and created Batch file in separate folder with one line “C:\TurbSim\TurbSim_v2.00.exe %1 %2”.
I am not able to get where I am missing. Can you please suggest where the problem is?
Thanks,
Best regards,
Dear Mohd,
You should only need the TurbSim input file, unless you are using advanced features such as the coherent structures.
Can you place the TurbSim executable in the same directory as your TurbSim input file and run it there? For example, if you have TurbSim_v2.00.exe stored in C:\TurbSim, along with the input file, turbsim.inp, does typing work?
C:\TurbSim\TurbSim_v2.00.exe turbsim.inpBest regards,
Thanks, Dr. Jonkman for the solution and reply. It worked 
Hello Dr. Jonkman,
Can we use the turbsim user defined spectral model “USRINP” and “TIMESR” for tidal specific cases ? I have my own data both as freq vs spectra and time series data.
If we can, then in that case I have my own tidal shear profile which i need to input in windprofile “USRINP”. Can we do that instead of using H2L ?
Thanks.
