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?
Hi again, Kendrick,
Thank you for sharing the results. Following the messages, there are some properties that were not correctly defined. One of those could be the panel thickness. The solver output is also mentioning zero-length members, so running an Integrity check could also help.
Considering this situation, we recommend opening a support ticket by sending an email to: hwsupport@Altair .com, sharing your current file, and we can take a closer look at it.
