Using CFD methods to simulate the IEA 22MW wind turbine

[qwer2586]

I am currently using CFD methods to simulate the ​​fully coupled aero-hydrodynamic analysis​​ of a semi-submersible IEA 22MW wind turbine. The total mass of the wind turbine I am using is 23,984,100 kg, and center of mass（CM）of IEA 22MW wind turbine is 0.2 m above the sea water level (SWL). The moment of inertia values are as follows: Ixx = 7.5273 × 10¹⁰ kg·m²（wind turbine roll inertia about CM）, Iyy = 7.5045 × 10¹⁰ kg·m²（wind turbine pitch inertia about CM）, and Izz = 4.3693 × 10¹⁰ kg·m²（Yaw inertia about wind turbine centerline）. I would like to know if these settings are correct. Thank you！

If possible, could you please provide motion response data of the IEA 22MW wind turbine under wind and wave effects?

There are a lot of possibilities depending on which components your calculations include and which coordinate system is used. These are not values we keep readily available. You can look in the original report or the Documentation folder for the Excel file that has some of the values you listed. Otherwise, you might double check against one of the model outputs. A WISDEM run might be the quickest way to compare your values.

Thank you，The parameters(Linear density,Extensional stiffness) for the mooring system in the GitHub file (OpenFAST/IEA-22-280-RWT-Semi/IEA-22-280-RWT-Semi_MoorDyn.dat) appear inconsistent with those in the paper (Definition of the IEA Wind 22-Megawatt Offshore Reference Wind Turbine). May I ask which set of parameters would be more appropriate to use?

And what I would like to know are the overall mass of the wind turbine(Include Rotor-nacelle assembly,Tower and Semisubmersible Floating Platform), the position of the center of mass( relative to the sea waterlevel), and the moment of inertia relative to the overall center of mass.

See #98 on the mooring numbers.

I do not have the mass numbers you are looking for, sorry.
