Second order effects

Is there a way to see the second order share of forces when doing a non-linear analysis?

The easiest way is to define 2 analogous load cases - one linear and another with second order effects.  Second order effects are visible  when comparing results for them.

 

Another possibility is to activate for non-linear load cases to save results after each load increment. Using these results the advanced diagrams can be displayed showing for instance force-displacement relations when incrementing the load. Increasing the number of load increments results in improving quality ("smoothing") or these diagrams.

See the attached screen capture showing what to modify and the example of diagram.
