Can't solve for some type of results

Why do I get this error sown in attachment? I try to add strain to results and I can't calculate it. The icon stays grey. Same for principal stress except that there is also NO at "Field variables that it depend on exist".

Comments

  • Strain and principal stress aren't available for beams with the internal solver, sorry. Only the longitudinal stresses.

    You could use the CCX solver which does produce general 3D stress and strain for rectangular and circular beam sections. Be sure to refine the mesh enough.

  • Ok. Thanks for answer.
