Switching to generic blade surfaces (rectangular airfoil, constant chord)

Dear Jason,

Why does OpenFAST switch to generic blades surfaces (rectangular airfoil, constant chord) sometimes during simulations? Is there a switch to avoid this from happening ?

Dear @Rahul.Ramachandran,

If you are outputting surface visualization from OpenFAST (VTK_type = 1) and AeroDyn is not enabled, you will get this warning when using ElastoDyn to model the blade structural dynamics (you’ll get a similar warning about BeamDyn when using BeamDyn to model the blade structural dynamics). This is because the airfoil geometry that can be visualized can be specified within AeroDyn, but ElastoDyn and BeamDyn have no inputs related to the airfoil geometry, so, their visualization is left as a generic rectangular airfoil.

Best regards,

It’s clear,

Thank you for your help Jason.
