Hi everybody,

I wonder if it is possible to run post-buckling analysis at COSMOSAdvanced Proffesional.

I've already started using the non-linear solvers static anddynamic. When I control the force calculations stop when bucklingoccures that I think is the result of some singularites. It allowsme to find the buckling (critical) load however do not show thebuckling mode.

I've started control the load by arc-length basing on theinformation presented in Cosmos Tutorials and sometimes go furtherwith the load. However, I still have problems with interpreting theresults. Is the decrease of the load means buckling? It not alwaysvery sharp decrease as I expected from real-life experiments.

I know it is a very difficult subject but I'd would be grateful forany comments and suggestions.

PS. My interests are cold-formed thin-walled beams but alsorotomoulded tanks made of polyethyleneSolidworksSimulation
