Abnormally large eigenvalue for linear buckling analysis

[apal21]

Hello,

I just did a linear buckling analysis for my situation and got a value of around 4e37 for the lowest eigenvalue. This is huge! So huge in fact, that I cannot use it as a starting value for my post-buckling analysis. The computer only handles as large as 1e36. Can someone please explain why this is happening, and how I can correct for this? Is this a question of units in Abaqus?

Maybe your applied loads are really small? Or tensile? Or your units are all messed up?

Most likely dimensions, material data or load values are incorrect. Take a closer look at them. Also, please share a picture of your model, if you can.
