Deflection

Postby Patricia.Pereira » Wed Jan 02, 2019 10:39 am

Hello,

I would like to know if the calculation of the blade deflection is made with a linear or cubic distribution of properties .

Thank you very much!

Dear Patricia,

I'm assuming you are asking how the distributed mass and stiffness specified in the blade input file of the ElastoDyn module of FAST/OpenFAST is interpolated to the blade analysis nodes? This is simply linear interpolation.
