IECWind

Dear Jason,

Thank you for your answer. Then I’ve misunderstood the input description.

Best regards,

Dear Jason,

I’ld like to generate discrete wind files for IEC design load cases using IECWind. I follow this link
http://www.nrel.gov/wind/nwtc/iecwind.html
Unfortunately I couldn’t find any executable on this page.
May I have IECWind archive?

Thanks in advance.

Best regards,
Moe Moe

Dear Moe Moe,

The new NWTC Information is still being updated. In the interim, I’ve placed an archive of IECWind v5.01.02 on my Google drive: drive.google.com/drive/folders/ … sp=sharing.

Best regards,

Dear Jason,

Thank you very much for your quick help. Now I’ve downloaded the archive of IECWind from your Google drive.
I tried to run the application, unfortunately it wasn’t successful. I’m running a 64-bit version of Windows and I’m afraid that the executable probably isn’t compatible with my operating system?

Thanks & Best regards,
Moe Moe

Dear Moe Moe,

There should be no problem running a 32-bit Windows executable on a 64-bit Windows operating system. What problem are you running into?

Best regards,

Dear Jason,

Thank you very much for your time. Sorry for disturbing you.
When I run the executable from the batch file, I got this error message “this app can’t run on your pc, to find a version for your pc, check with the software publisher”. That is what I used to get when I run a 32-bit Windows executable on a 64-bit version of Windows. This is why I come up with this question.
I couldn’t figure out why I can’t run the application.

Thanks & Best regards,
Moe Moe

Dear Moe Moe,

Hmm; I’m not sure. The source code is provided along with the compiled Windows executable. Can you recompile yourself using the source code?

Best regards,

Dear Jason,

Thank you very much for your suggestion.
As you recommended, I recompile the source code using MinWG-w64 compiler. (wasn’t successful using visual studio 2017 fortran compiler previously). Finally, the application is properly running.

I was able to build with Visual-Studio2020 by creating a new fortran project as ‘‘Main Program Code’’ (fetched by toggling the language filter to Fortran) in VS and pasting the IECWind.f90 source code into the newly created sample ‘.f90’ file. After saving the file used ‘‘Build Solution’’ command to obtain ‘’.exe’’ file in the newly built ‘Debug’ file at the specified project location. (I have intel parallel studio compiler installed)

Good morning,

As discussed in the recent posts on this thread, I built my executable for IEC Wind using Visual Studio and Intel Fortran Compiler (I had the same problem as Moe Moe). I now have the executable in the “debug” folder inside the project location. However when I try to run it, I get the following error -

Microsoft Windows [Version 10.0.18363.1198]
(c) 2019 Microsoft Corporation. All rights reserved.

C:\Users\VishalSairam>“C:\Users\VishalSairam\Power Curve\Power Curve ApS - Files\R&D\openFAST\Exe_Files\IECWind\IECwind\Debug\IECwind.exe” “C:\Users\VishalSairam\Power Curve\Power Curve ApS - Files\R&D\openFAST\Exe_Files\IECWind\IECwind\Debug\IEC.ipt”
Cannot find file “IEC.IPT” in the current directory.

I have copy pasted the IEC.ipt file in the same location as the executable and still I got the same error. It would be very helpful to have some input on this issue.

Thanks in advance,
Vishal

Dear Vishal,

Do you get the same problem if you change the active working directory (CD) to “C:\Users\VishalSairam\Power Curve\Power Curve ApS - Files\R&D\openFAST\Exe_Files\IECWind\IECwind\Debug” and then type in the command prompt?:

IECWind.exe IEC.ipt

Best regards,

Dear Jason,

Thank you very much for your input, that resolved the problem :slight_smile:

I am still unsure though, if I drag the openfast/TurbSim executable and the corresponding input file in the command window it works without having to change the directory in the command window whereas the IECWind executable does not (even though I built the executable in the same way). Would be nice to have your input on this :slight_smile:

Best regards,
Vishal

Dear Vishal,

I think when you drag a file into the Command Window that the path gets copied automatically.

Best regards,

I’ve now also recompiled a Windows executable of IECWind from the source code and you can find that here: drive.google.com/file/d/17IJ0vP … sp=sharing.

Dear sir,
I generated wind file by IecWind,I get the .wnd wind file,so which module should I put the file into OpenFAST to run?
Best regards,

Dear @Hairui.Jiang,

Wind data is specified in OpenFAST within the InflowWind module input file.

Best regards,

Dear sir,
Thanks for your reply, but I tried to utilize InflowWind and failed, what should I set the type of wind to? Where should I put the .wnd generated by iecwind in InflowWind?
Best regards,

Dear @Hairui.Jiang,

IECWind generates files in the uniform wind format. You should use WindType = 2 and specify your *.wnd file using Filename_Uni.

Best regards,

Dear sir,
Thanks for your reply,I would like to ask what “V”、“H”、“+”、“–” and “1.5”stands for,
Best regards,

Dear @Hairui.Jiang,

“V” and “H” refer to “vertical” and “horizontal” in this deterministic Extreme Wind Shear (EWS) transient. “+” and “-” refer to “positive” and “negative” shear. “1.5” refers to IEC design load case (DLC) 1.5.
