Hi Oguzhan,I solved this to near completion. I ended up with non convergence at around 0.92, after reaching 0.97. The point load ended up causing further assymetry, final result shown below. The max deformation is occuring where I have applied the point load. This may not be the result you are seeking, so I would probably return to using the buckled shape.nn1 - I applied 0.02 MPa.n2 - I used arclen,on. however based on the non convergence you may need to play around with theMINARCvalue to get through to convergence.nnFor my own understanding, is it expected that this structure ever becomes stable again? if it is not, the solve will never reach convergence, however you can still plot the force deflection curve for part of the buckling process. nnn
