Instructions for Compiling FAST

Dear @Jason.Jonkman

Thank you for sharing the file. I was able to compile FAST using the instructions.

However, I want to run FAST with Simulink. For that I assume that I also need to compile FAST_SFunc.mexw64. Are there any instructions available on how to do that?

Kind regards

Dear @Narender.Singh,

Iā€™m not aware of separate instructions for compiling FAST v7 in Simulink, but a MATLAB script for compiling is found in the folder Simulink/Source of the FAST v7 archiveā€”see make_FAST_SFunc.m.

Best regards,

Dear Sir,

I am unable to compile FAST v7 Seismic Modules using the makefile provided. It shows me an error in the Random_Seed (PUT = xxxx) at line 1480. It seems like this is a compiler error that comes up while using GFORTRAN to compile using makefile.

It would help if you could provide me with FAST v7 (with monopile capability) sources and seismic source files again.

Thanks

Dear @Kashyap.Subham,

See my post dated Jan 30, 2023 in the following forum topic: Instruction for the Seismic fast version.

Best regards,

Dear Sir,

I am using the same files as on the post referenced by you. The error still persists when I try to compile FAST v7 with the seismic module.

Sorry, but I donā€™t have any experience compiling in gfortran. Perhaps try a different compiler such as Intel Fortran within Visual Studio, which is free?

Dear Jason,

I have a question about precompiled binaries of OpenFAST for windows, and specifically 32bit versions.

I see that ā€œopenfast_Win32.exeā€ was provided for OpenFAST v2.5.0. But for later versions, there is only openfast_x64.exe (64 bit version). Is there a specific reason for that ? is it even possible to compile later versions of OpenFAST in windows for 32bit application?

The reason is: I have a commercial WTG setup, which I was running with openfast-3.5.1, with 64bit windows executable. Now I have a Bladed controller DLL, which requires a 32bit windows executable (as understand from Bladed website). However, I am struggling to compile openfast-3.5.1 in windows, for 32bit. I hope it was clear, thanks in advance.

Dear @Salur.Basbug,

Iā€™m not sure what issue you are running into, but you should be able to compile OpenFAST for 32-bit Windows operating systems, as we have done and shared in the past. However, with 32-bit versions, please be aware that your models may be limited in size/discretization given memory limitations in 32-bit Windows.

Best regards,
