Cable Models in Hypermesh

I'm currently working on a project for my studies, and one of my tasks is to find different ways to model cables in FE programs (preferably Hypermesh). I've already found several options:

Cables as forces

Cables as truss elements

Cables as rigid body elements

Cables as nonlinear CGAP elements.

Can you think of any other options?

    Hi,

    if running a non-linear analysis, you can use CBUSH elements with a non-linear spring stiffness curve, similarly to the CGAP elements.

    You could provide a curve such as for compression it has really small stiffness and for tension it has a "regular" stiffness.

    Additionally, just like truss elements, you could use bar/beam elements and release some DOFs at the ends, in example, releasing rotations, i.e.
