How to download openfast x64 double precision for windows?

[OpenFoam-User]

Hello,

I downloaded openfast 3.5.3 from the releases page (here). However, when I run the command openfast_x64.exe /? I get the following output that indicates single precision:

OpenFAST-v3.5.5
Compile Info:
 - Compiler: Intel(R) Fortran Compiler 2021
 - Architecture: 64 bit
 - Precision: single
 - OpenMP: No
 - Date: Dec 21 2024
 - Time: 15:51:59

Where can I find a double precision version of openfast for Windows (without compiling it from source)?

Thank you

Dear @OpenFoam-User,

NREL has not provided precompiled Windows executables of OpenFAST in both single and double precision. Single precision is typically fine for engineering use given that the internal variables needing double precision are stored as doubles even when compiling in single precision. If you want to compile fully in double precision, you'll need to compile from the source. (In my opinion, compiling with Intel Fortran through Visual Studio is the simplest on Windows).

Dear @jjonkman,

Many thanks for your reply. So I have to compile OpenFAST myself in double precision.
I am a bit confused by:

NREL has not provided precompiled Windows executables of OpenFAST in both single and double precision...

I've downloaded OpenFAST single precision version from the current repository as I linked in my first post (which I suppose belongs to NREL).
Best regards,

I should have said that NREL provides precompiled Windows executables of OpenFAST in single precision, but does not provide them for double precision.
