Gravitational acceleration component in local blade sectional accelerations

Is it correct that the Gravitational acceleration component is not included in the local blade flapwise and edgewise accelerations (e.g. Spn9ALxb1 , Spn9ALyb1)? Is it still the case that blade (structural) accelerations are computed relative to the inertia frame; they do not include the gravity effect? Is this true for both Elastodyn and BeamDyn?

thank you and best regards,

Dear @Imad.Abdallah,

Yes, that is correct.

We should add an option in the future to output the accelerations including gravity. Perhaps you could add this as a feature request in the OpenFAST GitHub issues page: Issues · OpenFAST/openfast · GitHub?

Best regards,
