zsh: segmentation fault openfast IEA-15-240-RWT-Monopile.fst

[Ssurya013]

Hi,

I am new to OpenFAST platform. I am running OpeFAST from my Mac. I cloned the IEA-15-24-RWT develop branch. I changed the path for libdiscon.dylib in the servodyn file. While running the .fst file I get the following warnings and errors. May I ask how to resolve the warnings and errors, please?

(openfast_env) sb01@P6Q22Q IEA-15-240-RWT-Monopile % openfast IEA-15-240-RWT-Monopile.fst

Hello,

I just posted an update for ROSCO v2.8, so that might help with you error. If not, we cannot anticipate all possible combinations of compilers and OS versions, so you might need to compile the ROSCO library yourself from its source.

Cheers, Garrett

Hi Garrett,

Thank you for the update. I was however getting the same set of warnings and errors even after the update . I then compiled the ROSCO library from its source, still it did not solve the issues. The 15MW UMaineSemi within ROSCO repository Test_Cases runs without any issues. I then compared the input files for both the cases and found out that there are a few variables those were missing in the input file compiled by ROSCO for the monopile case. After adding those variables manually, the monopile model now runs without any issues. Thank you very much for your time. Much appreciated.

Cheers, Surya

Hi Surya,

I am glad to hear that things are working although I didn't fully follow your last comment. If there are corrections that need to be posted to one of the repository files, please let me know.

Cheeres, Garrett
