Nonlinear buckling of a cylinder by riks in Abaqus, introducing imperfections from buckle

In this video using imperfections from buckle analysis nonlinear buckling of a cylinder under hydrostatic pressure is investigated by riks step in abaqus. Mode shapes from buckle analysis were introduced as imperfections. It is shown that how we could define imperfections in a riks analysis. You can find the buckle analysis procedure in the following video:
• Linear buckling of a c...

    Hi. What is the geometric boundary condition of the structure?
