Derived Results of node coordinates

How to get torsional angle on solid elements for torsinal stiffness analysis? I try to use 'derived results', but I can't expression node coordinates in cylinder system.

Hi,

 

Have you tried to output rotation displacement?

 

During pre-processing in OptiStruct (assuming you are using OptiStruct) Goto Analysis page>> Control cards>> global output request>> displacement>> Add rotations (ROTA)
