How do you Insert a FEM buckling perturbation into a FEM cylinder?

[BuckTU]

Hi Fellow engineers,

If you run a buckling analysis and you want to use the buckling mode. To introduce a small buckling perturbation. Where do you have to look at?

Eigenvalue and/or Eigenmodes? Is the (negative)frequency of any importance?

Thanks in advance.
