We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello, 

I would suggest creating two new discrete beam elements (ELFORM = 6) with a material MAT_GENERAL_NONLINEAR_6DOF_DISCRETE_BEAM (MAT_119).

The 1st beam element between the nodes 11 and 22 may have very high stiffness (almost rigid) in translational DOF stiffness (LCIDTR, LCIDTS and LCIDTT) thus the nodes should be able to rotate.

The 2nd beam element between the nodes 1 and 2 may have prescribed known rotational DOF stiffness (LCIDRR, LCIDRS, LCIDRT) and very low translational DOF.

Please let me know how it goes,

Thanks,
Alex
