Cell Periodicity applied to buckling

Hello, I'm studying failure mechanism of periodic honeycomb structures. The Cell Periodicity module introduced in Comsol 5.4 was very useful to calculate the homogeneized Young Modulus E. Now I'm trying to use it to study Linear Buckling and plastic collapse but I've been having some issues setting it up. Should I make a new study for Linear Buckling, or is it supposed to go inside the Cell Periodicity study I used for the E Modulus? Should I add a for the buckling or the modulus makes one automatically? is it even ok to use Cell Periodicity for this or should I just use Periodic Boundaries.
If it helps, what I'm trying to do right now is a comparisson with Gibson analytical models of failure of cellular materials with the results of a FEM model: https://ars.els-cdn.com/content/image/1-s2.0-S0021929004004919-gr6.gif
