Hello,

I am performing a SSD Modal Analysis on a plate and I do not know if I need to specify any boundary conditions in this step? This step is preceded by the frequency modal analysis step in which I specified my boundary conditions for my plate (that is free rotations)

Thanks in advance again :)
 
When the BC is created in the initial step (before the *Step + *Frequency) then it also counts for the other steps.

BC created in a perturbation step only acts within them.
BC in nonlinear steps propagate automatically to the next steps.
