Precompiled binaries

The binary files in this release were built with the Visual Studio solution files distributed with OpenFAST (not using cmake), using

• Intel Parallel Studio XE 2019 for Fortran (Update 5) with Microsoft Visual Studio 2017
• Microsoft Visual C++ 2015 (C) (v1.40), for build without Simulink interface
• Microsoft Visual C++ 2017 (C) (v1.41), for build in Matlab
• MATLAB Version: 9.11.0.1837725 (R2021b) Update 2

NOTES:

• The FAST S-function was built with a few changes to the source code to work around build errors (see bjonkman@5ca2b90):

  • = NULL was removed from the last two arguments in the definition of FAST_Sizes in FAST_Library.h:

  EXTERNAL_ROUTINE void FAST_Sizes(int * iTurb, const char *InputFileName, int *AbortErrLev, int * NumOuts, double * dt, double * tmax, int *ErrStat, char *ErrMsg, char *ChannelNames, double *TMax, double *InitInputAry);

  • The first &TMax argument was added to the call to FAST_Sizes in FAST_SFunc.c:

  FAST_Sizes(&iTurb, InputFileName, &AbortErrLev, &NumOutputs, &TMax, &dt, &ErrStat, ErrMsg, ChannelNames, &TMax, InitInputAry);

• FAST.Farm_x64_OMP.exe is built with OpenMP libraries and linked with dynamic libraries.

  • You will need this Intel Fortran redistributable package installed to run FAST.Farm_x64_OMP.exe if you do not already have Intel Fortran 2019 Update 5 installed. See the installation instructions here: https://software.intel.com/content/www/us/en/develop/articles/redistributable-libraries-for-intel-c-and-fortran-2019-compilers-for-windows.html.

• You may also need a redistributable library for Visual Studio installed. See instructions here: https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0

• The other OpenFAST executables DO NOT require these redistributable libraries to be installed. Instead, they were built with static libraries.
