Hello,
How do I release moments that are transferred from a 2D finite element shell onto a beam element supporting the shell elements (i.e. releasing the moment that is causing torsion on the beam)?
Thank you,
KC
Hello, Kendrick,
Thank you for reaching out. As a first approach, you can include the "Drilling Degree of Freedom", available in the Solver tab in Preferences (Setting menu —> Preferences…) .
This option controls the rotational continuity of the shell's local z axis, providing stiffness to this DOF.
Another approach might be using pinned constraint lines. There's a video exploring this topic:

Let us know how this works for you.

Is it possible to double a beam element as a pinned constraint line as well?
The Help section indicates this as possible, as can be seen:
For further information, we recommend visiting the "Pinned Constraint Lines" topic in the Help section (Help menu —> Contents…)
I was able to run this model of a shell supported by a beam across without the pinned constraint line:
When I add the PCL over the beam, it gives me these errors below. I was expecting a simply supported shell from the end to the beam support. Any ideas what I'm doing wrong?
