Buckling Simulation

Hi!

i have a small problem regarding NX Nastran... I have to calculate the critical load and the respective instability mode of a 2D beam. The beam is loaded from both ends, with P=1 and q(x)=0 and only rotations are allowed. 

I am able to draw the 3D beam (W130x23.8) on Nastran, but i don't know how to retrieve the critical load, as well as it's instability mode... Can someone give me a hand?Beam P1.png

 

Best regards

See the section on Linear Buckling in the NX Nastran User's Guide. The first example is an Euler buckling problem.
