Dear @Ali.Rouhbakhsh,
Presumably you are referring to the old scripts such as RunIEC and RunNTM, which are no longer supported by NREL.
Many users of FAST / OpenFAST who need to run many simulations have written there own scripts for their own purposes. For example, the scripts in the MATLAB Toolbox (GitHub - OpenFAST/matlab-toolbox: Collection of Matlab tools developed for use with OpenFAST) or Python toolbox (GitHub - OpenFAST/python-toolbox) can be used to read and write FAST input files, so–using these scripts–it would not be difficult to write your own MATLAB- or Python-based scripts to generate OpenFAST input files for a large set of cases based on a master set of OpenFAST input files. This topic was discussed a bit here: #573.
The Systems Engineering team at NREL also developed the AeroelasticSE module of WISDEM to automate the running of many of the IEC DLCs. These scripts are in the process of being overhauled and migrated into the new WEIS framework to support integrated loads analysis, design, and optimization of wind turbines–see: GitHub - WISDEM/WEIS: Wind Energy with Integrated Servo-controls Toolset.
Best regards,
