Dear Bruno,
Yes, I agree.
I’m not aware of a MATLAB-based writer of TurbSim binary (*.bts) formatted wind data files, but there is a MATLAB-based reader, readfile_BTS.m, in the MATLAB Toolbox: github.com/OpenFAST/matlab-tool … /Utilities. I’m sure with a bit of work, this script could be updated to become a writer. Of course, there is a Fortran-based writer inherent within the TurbSim source code.
Searching this forum, I also recall a user posted a MATLAB-based writer for Bladed binary wind (*.wnd) formatted wind data files–see: binary .wnd specification - #7 by Simon.Fobe.
Best regards,
