What's the exact meaning of HubIner?

Dear @Nitin.Sivakumar,

If I understand correctly, you are comparing the rotor inertia computed by the structural model of FAST v7 against the results from ElastoDyn in OpenFAST. I’m not exactly sure I can pinpoint why this change exists, but regardless, the difference is about 0.2%, and so, is not too concerning either.

Best regards,
