coming soon

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

• Intel Fortran compiler (ifx) 2025.1.0 with Microsoft Visual Studio Community 2022
• Microsoft Visual C++ 2022 (C), for build in Matlab
• MATLAB Version: 24.2.0.2863752 (R2024b) Update 5
• Executables with _OpenMP or _OMP in the name are built with OpenMP libraries and linked with dynamic libraries.
  • You will need this Intel Fortran redistributable package installed to use these executables if you do not already have Intel Fortran OneAPI 2025 installed. See the installation instructions here.
  • You may also need a redistributable library for Visual Studio installed. See instructions here.

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