Thanks for the answer IceBreakerSours.
Thats the thing that i dont understand.. because this anlaysis is giving me some eigenvalues..
Now, if I change the mesh.. For instances using, lets say 1000 elements in one analysis and 6000 elements in the second analysis, the resulting eigenvalues have a...

In the step-module i have chosen "buckle" as the type and eigensolver as Lanczos with 6-7 eigenvalues.
I should remind that i am a new user in Abaqus, few months of experience...
