Modeling thin-walled beams: Abaqus falls short

I am looking into modeling of thin-walled beams (in the context of preparing for a structural-analysis course). Abaqus is really disappointing in this regard. For instance, warping dofs cannot be manipulated in the CAE; they cannot be visualized in postprocessing; the rotation of the cross-section is not displayed correctly in postprocessing.

What is your experience?
