rotate cross section of a beam

[luca_t]

Bye to all,
I wonder if you know a way to turn a cross section of a beam. in particular the beam already is meshata. in reality there is the reverse normal command, but it is only useful in the case of a rotation at 180°.


thanks to all

What element are you using?
beam3, beam4 or "new technology" elements like beam188 beam189?
In the first case, you may think about modifying real constants by inverting them.
otherwise you have to work with the "sections" (see guide)

thanks stefano for the answer.
I am using beams 188.
in my case the mesh is already realized. If not, I could have used to check the "pick orientation keypoint" option during the line meshing.

to the mesh of the beam is coupled a geometry (linea).
rotate geometry with a cylindrical reference system and the mesh consequently should turn according to the angle you want. :finger:

here is a simple example :finger:

Thank you!
