Sorry for putting this up here again. How can I generate the operational natural frequencies using FAST v7. I want to get the natural frequencies and their modal participation factors to start with. It would help if I could get a reference to a relevant post for a step-by-step procedure, if any.
There are many topics on this forum focused on how to compute full-system mode shapes and natural frequencies with FAST v7, as well as with newer versions of FAST/OpenFAST, via linearization, followed by post-processing via MBC3 and eigenanalysis. See, e.g., the following forum topic: Eigenanalysis FAST.
