Hi,

I have modeled a shell composite layup,each element has its own coordinate system and I am trying to get the stress resultants as the output of my analysis.

I would like to know in which coordinate system the results are shown by default.

I know that if I choose layup orientation S11 (stress) is shown in the fiber direction but I can not understand SF1( stress resultant) is shown by default in which coordinate system?

there is no difference between SF, SK, SE in default or layup coordinate system.

if I want to get the results in the local coordinate system what should I do?
