Linear Buckling under GRAV loading

I want to create the buckling analysis for the same.

I have used GRAV card for loading. I want to carry out the buckling for the same.

But I am not able to see the results for linear buckling. 

Will you please help to resolve my problem.

    Attention: if your beam is loaded under tensile mode, the buckling phenomenon maybe never occurs.

    Now, It shows buckling modes by making the load GRAV in -Z direction.

    but it still does not show  stress and displacement due to buckling

    Generally inertia load alone would not contribute much to the buckling modes or in determining critical loads.
    However, if you would like analyse only with inertia or gravity load create a load collector by card image GRAV and put the G value and the direction to it.
    Call this load in the static subcase.
    For subacse 2 select the type as Buckling analysis and under STATSUB(PRELOAD) pick the static subcase I'd.
    Buckling modes and eigen values are printed by default.
