Cylindrical Joint in Optistruct
Altair EmployeeHello,
I am trying to add a cylindrical joint between two parts and apply a moment onto one part, something similar to a Hinge
But the elements tend to collapse (expand and scale up) and not stable
I have tried Cbeam elements with torsional moment as negligable, but having the same effect
Can you let me know how to create stable joint in Optistruct
Thanks and Regards

Joints option is available for Optistruct MBD analysis.Refer optistruct MBD analysis tutorial for same.You have setup simple static analysis where structure would tend to deform upon loading.

Maybe you can use an SPC and release the DoF to realize as a cylindrical joint. For instance, a cyl joint along X axis (translates in X and revolves around X) release Dof 1 and 4. Try as a work around.
Altair EmployeeThank you Rahul for the time and clarification
Will check out the MBD option and see how to best suit for my condition
Thank you Prakash, but with SPC I don't want to restrict the surrounding parts movement
What is the end objective of analysis?
could you share .fem file?
