The error message sounds related to the formatting of the MoorDyn (MD) input file. My guess is your MoorDyn input file is not formatted for the version of MoorDyn (v2) that you are using. I would suggest switching to the most recent version of OpenFAST (v3.5.1: https://github.com/OpenFAST/openfast/releases/tag/v3.5.1), as well as the most recent version of the IEA Wind 15-MW reference wind turbine (v1.1.8: https://github.com/IEAWindTask37/IEA-15-240-RWT/releases/tag/v1.1.8)
Best regards,
MaoDodo-T
Hello! I am trying to run a simulation of the UMaine VolturnUS-S (FOWT) semi-submersible supporting the IEA-15-240-RWT wind turbine. I've encountered many problems, but even after referring to the issues in#1398 sequence, I still cannot run it. The following is the error I encountered after running. OpenFAST
