Hello, is there a more detailed description of this stall model available?

Dear @Matthias.Maerz,

Do you mean more information than what is available in: 4.2.1.8. Unsteady Aerodynamics — OpenFAST v3.5.2 documentation?

Best regards,

Dear Mr. Jonkman,

I read the documentation and had a look into the source code (UnstaedyAero.f90):

For the 4 state HGM model I found a paper referenced (Dynamic inflow and unsteady aerodynamics models for modal and stability analyses in OpenFAST,

Journal of Physics) that provides a detailed view to the theory. Is there also such a document for the 5 state HGMV model available?
Best regards,

Dear @Matthias.Maerz,

I’m not aware of an NREL publication where the 5-state model is described.

Best regards,
