Dear @mohsamaz, Which operating system are you running on? Is the ROSCO dynamic library (libdiscon.so) stored in the location you've specified (in the lib directory three directories back from where you are running OpenFAST? Best regards, |

Dear @mohsamaz, Than you are using the wrong dynamic library of ROSCO. A dynamic library (shared object) has a .so extension on Linux, but on Windows, the dynamic library should have a .dll extension. You can find precompiled dynamic libraries for Windows of various releases of ROSCO here: https://github.com/NREL/ROSCO/releases. Best regards, |

Dear Dr. @jjonkman, As you said, I downloaded ROSCO-2.9.5 from https://github.com/NREL/ROSCO/releases, but I got the same error: 1- ROSCO-2.9.5 OpenFAST-v3.5.3
OpenFAST input file heading: Running ElastoDyn. FAST_InitializeAll:SrvD_Init:BladedInterface_Init:The dynamic library .../../../lib/libdiscon.so OpenFAST encountered an error during module initialization. Aborting OpenFAST. Also I downloaded ROSCO-2.8.1 and I got the error: OpenFAST-v3.5.3

Dear @mohsamaz, Regarding your ROSCO v2.9.5 download, it appears that you are again using a .so file rather than a .dll file needed by Windows. Regarding your ROSCO v2.8.1 download, the input files you are using from the Examples/Test_Cases/NREL-5MW directory of the ROSCO archive do not appear to be compatible with OpenFAST v3.5.3. I'm not sure which version of OpenFAST these cases are valid for, but you can always format the input files to be compatible with specific releases of OpenFAST by following the documentation from here: https://openfast.readthedocs.io/en/main/source/user/api_change.html. Best regards, |

Hi @mohsamaz , Were you able to run ROSCO? Do you think you could be kind enough to share a video or step-by-step of your screen on how you are able to use ROSCO? Thanks! |

Hello,
Hello,
I am currently working with ROSCO and noticed that the TestCase folder contains several cases, including the NREL-5MW. Inside this folder, I found the NREL-5MW.fst file, which I would like to run.
Here’s what I attempted:
Navigated to the NREL-5MW folder.
Used Shift + Right-click to open the context menu.
Attempted to run it using the openfast_355.exe (OpenFAST version 3.5.5, located in another folder).
However, I’m not sure if I’m doing this correctly. Could someone guide me on the proper steps to run this test case, or let me know if additional configurations are needed?
Thank you in advance for your help!
