Installation of OpenFAST

[Shankar.Sarpate]

Dear All,
I was trying to install OpenFAST as per the attached procedure. There is an error while setup downloading (error message attached).

Please suggest me any other site for downloading the software other than http://www.gtlib.gatech.edu

Thank a lot!

Dear Shankar,

I'm only really familiar with Building OpenFAST on Windows with Visual Studio, which is the procedure I'd recommend if you are using Windows.

For specific questions on using Cygwin to install and build OpenFAST, I suggest posting your question on the OpenFAST issues page, where the OpenFAST development community can support you: https://github.com/OpenFAST/openfast/issues. Not everyone in the OpenFAST development community checks this forum regularly.

Best regards,

Dear Jason,
Thank you very much for the guidance!

Now I am working on loads calculations project with IEC 61400-1 Ed3.
In the sample projects, we have limited number of wind conditions simulated. Is it possible to through light on the following points:
1. How we can consider all load cases / simulations running in batch files?
2. Can we assign more than one wind files for one simulations keeping other parameters same?
3. How to generate *.wnd file?

I am going through the FAST manual. And trying to get answer to the above question. Meantime can you provide above information if possible?

Thanks in advance!

Regards,
Shankar Sarpate

Dear Shankar,

Normally users develop scripts to run multiple FAST simulations e.g. to simulate multiple wind conditions for the same wind turbine. This has been discussed several times on this forum e.g. viewtopic.php?f=4&t=1938&p=10093 and viewtopic.php?f=4&t=603.

By a *.wnd file, presumably you mean the turbulent wind data file in binary format. (The turbulent wind binary file in Bladed format typically has the *.wnd extension.) However, unless you plan to use Bladed, I would recommend using the TurbSim binary format *.bts. Regardless, both types of turbulent wind data files can be generated using TurbSim: https://nwtc.nrel.gov/turbsim.

Dear Mr. Jonkman,

I'm not sure if this is the correct thread but I am starting off to use FAST for my PhD studies in offshore energy storage for FOWT and not sure if I should start off with Fast ver. 8 or Open FAST.

What do you suggest please?

Dear Peter,

For any new project, I always recommend starting with the newest version of the software, which in this is the release of OpenFAST v2.1 (master branch). All current and planned FAST development is taking place in OpenFAST.

Best regards,

Thanks Dr. Jonkman. Managed to compile OpenFAST.
I now have problems in getting to have the openfast.exe file recoginize input files. Anywhere where I can get some help?

Thanks,
Peter

I have cloned the https://github.com/OpenFAST/r-test files.

What would be the next step please to read these files and have OpenFAST work on them?

Thanks

Dear Peter,

If you are asking about running the tests to ensure that OpenFAST is compiled and runs properly, please read the OpenFAST testing documentation: https://openfast.readthedocs.io/en/mast ... index.html.
