buckling deformed beam

hi,

i have a simple column with pinned  botom (ux,uy and Rz fixed) and a roler at z axis at the top (ux uy fixed).

i apply a vertikal load at the top and the calculation mode is non linear p-delta.

my question is why i do not see the colunn buckling and deformation?

i only see the displacement in the z axis at the top but no bending. the buckling analysis show that the column is under excesive force but even if i increase the load in very large amounts the deformation is only axial.

 

is there a way in robot to see the REAL deformation  and bending or torsional  behavior?

what am i doing wrong?

thanks
