Hi all,

Currently I'm modeling a beam subjected to an axial torque with the beam element B31OS. When I add boundary conditions to the nodes, it is only possible to restrain the translations and the rotations, but not the warping. The warping is here the 7th DOF of each node of a B31OS element. I didn't activate a warping option or something similar, as I am not aware of its existence.

Is it possible to restrain the warping using Abaqus/CAE? Or is the GUI for setting the BCs always the same, even when an element supports warping?

Thank you in advance!

Greetings Nick
