Dear @KanwarOsama.Zulfiqar,
Both of these matrices look a bit off, e.g., because i would expect the (1,1), (2,2), and (3,3) elements to be identical and equal to the RNA mass, which is 350,000 kg for the NREL 5-MW baseline wind turbine. I’m not fully sure what you have done wrong (without reviewing all of your files in detail), but please find a similar discussion the following forum topic: Rotor and Nacelle Mass moment of Inertia Tensors.
Best regards,
