I am trying to get the buckling lenghts from a certain model, but when i try to connect the Buckling Modes component, its tells me the following error:
- The model has no second order forces NII defined for which a buckling load factor could be computed.
I made a simple beam that has fixed supports at the ends. The buckling lenghts should be Lbuck < Ltotal. But it tells me at the results that the Lbuck = Ltotal. How can i fix this? Is there a way to change the buckling lenght or to make it automaticly change it for the given/calculated beam?
