Prestress ANSYS WB, ASME Sec VIII Div 2, Buckling Check


I'm trying to practice Example E5.4 from PTB-3-2013 in Workbench (protection against collapse by buckling)

How does one apply a pressure to create a prestressed state, then add a perturbation and then get the eigenvalues from the elastic buckling solution? I believe the pre-stress from the eigenvalue buckling analysis will take either the initial pressure or the perturbation.

Thank you
