You can extract only the positive buckling factors and modes for a
model that you use to run a buckling study.
The option Extract
positive buckling factors only is available from the Buckling Study Properties dialog box.
If
you choose to extract only the positive buckling factors and modes, the solver switches
to the Automatic option. SOLIDWORKS Simulation
does not report any negative buckling factors and their associated modes that the solver
could calculate for the buckling simulation.
