What changes need to be made to model a land-based 5 MW wind turbine in the FAST v7 Seismic Module? Presently, I use the rigid base foundation files. I would assume that the platform reference points and CM must be zero in addition to the tower draft. Moreover, Do I need to change the mode shapes of the tower for a land-based turbine? If yes, can you provide me with the necessary tower mode shape file for the land-based turbine for the 5 MW baseline turbine? Just to reiterate, I am using FAST v7 Seismic Module.
