Eigenfrequencies of IEA-15-240-RWT-Monopile Blade & Full System

Dear NREL Team,

I am currently modeling the IEA-15-240-RWT-Monopile in Simpack. In order to validate the rotor blade I compare the Eigenfrequencies from Simpack with data from


and also from natural frequencies from linearization run with OpenFAST.

While there is good agreement of the full system Eigenfrequencies with OpenFAST, the blade edgewise natural frequencies differ up to 15 % from those two papers. The flap-wise are in good agreement.

According to the release notes you updated the mass and stiffness properties in v1.1.

Was this update after the publication of those two papers?

And if so, do you have also the new natural frequencies of the blade with the updated properties you could share?

With kind regards
