I have built shell model of a wind turbine rotor in Abaqus CAE and i have run modal analysis. I see that the first natural frequency is around 1 Hz which is sensible but the displacements are very small 10^-12 which does not make much sense. Max Displacement in the model is always 1 in modal analysis. I am not sure how it is 10^-12 here. Since, the displacements are so small, I cannot increase the scale factor (Exaggerate) for visualization to see where is the problem.
