Torsion problem with ASTER

You're right, if I import the .unv the groups are visible. I get to work then.

Thanks Claus, I managed to apply a torsion moment. I considered a plate and created a node and relying it as saw in your example with edges to the plate. The group of edges was declared as DIS_T and then
defined the 6 DoF, in K_TR_D_L.
Now, the problem is that I wish to use this mesh for an electromagnetic calculation, but the code that I use for that, only
accepts 3D elements.
Could you advise me somehow to manage to apply a torsion moment using 3D elements ?
I thought to create a node, in the same manner as in the working example and to rely it with a big element to the plate. I'll give it a try and see what it gives.
Thanks again !

The attachement.

For the moment I still use the rigid elements and a node where to apply the torsion moment.

I have an extra question, on how to recover the rotation angle with ASTER. A first survey of the documentation led me to the &quot;nom_champ: THETA&quot;, but it seems it is related to the sensibility calculation.

So, how is it possible to get the angle on a node ? Is it DZ (if my moment is applied around z-axis) of the field DEPL ?

Thanks again for your precious answers.

If I 'm not wrong, element type DIS_T only has 3 DOF (DX,DY,DZ).
In your case I would use element type DIS_TR that has 6 DOF then rotation around Z should be DRZ in field DEPL
