Hi Masri,


Based on the image you shared, can you please try changing the force to 1N in the static structural analysis? It is likely that the beam has no longer small deformation when you apply such a large load. 


Usually what we do is apply a unit load in the static structural module, and the buckling load will be whatever the load amplifier is in the eigenvalue buckling analysis.
