Sequence of rotation in tower top tilting

Dear @Jason.Jonkman

I want to ask what is the sequence of rotation adopted in openfast when considering tower tilt. I mean [rotation in fore-aft]*[rotation in side-to-side] or the opposite ?

Thanks in advance,

Best Regards,

Riad

Dear @Riad.Elhamoud,

The ElastoDyn module of OpenFAST uses small-angle approximations with corrections to support moderate angles up to 15degrees slope) for the tower and blade deflections, in which rotation sequence is not needed.

Best regards,
