Hi...
I am working on post buckling of a cylinder in ANSYS. I have included imperfections using NLGEOM command. I applied a load which is slightly higher than eigen value buckling analysis and i am using displacement controlled analysis using arc length method. I am getting the following error after certain time
"solution not converged
Arc length value has reached its minimum allowed value
Run terminated"
Can anyone please help me how to resolve this issue.....
