5MW Monopile CompServo Issue

Hi All,

I am running the 5MW OC3Monopile_DLL_WTurb_WavesIrr and I am receiving an error regarding CompServo. Have you seen this error or perhaps would know any troubleshooting tips? I am on OpenFAST 4.1.2. Thanks!

Best,

Elaine

Dear @Elaine.Liu

Could you please share your ServoDyn input file as well as your .fst input file ?

Best Regards,

Riad

Dear @Elaine.Liu,

My guess is there is incompatibility between the format of your OpenFAST primary (.fst) input file and the version of OpenFAST you are using. The changes in input file format between each release of OpenFAST are documented here: 4.1.2. API changes between versions — OpenFAST v5.0.0 documentation. And you can always enable the Echo option to debug issues associated with input file formatting.

Best regards,

Hi All,

Thanks for the helpful responses. Indeed it was a version issue. Upon updating to OpenFAST v5, the simulation is now running. @Riad, I am using the standard 5MW OC3 Monopile as listed in these r_tests.

Thanks again!

Best,

Elaine
