Hi,
I am running a free size composite buckling optimization with min mass as objective and buckling factor >2 as constraint but the analysis is not converging.
I am attaching both the input and output file for guidance.
Thanks

Please refer FAQ section for the optimization setup from OptiStrcut online help. PFA edited one for composites.
in this document it is mentioning base thickness value. what does it mean?
I want to impose a buckling factor constraint >2 but then i also realize that buckling factor can also be negative. So how can i define the constraint so that the first buckling mode should be optimized with a factor > +- 2?
