Hi all,

I am trying to model a cable net ideally with link elements connected with rotational springs. first i tried it with the original geometrie wich are s-shaped elements,  but that probably doesn't work with link?

when I tried it with straight lines and a out ouf plane force at nodes, it can calculate, but it doesnt show deflections, as seen in the pictures. I just fix corner nodes and it does how deflections for an in plane load.

Any ideas whs that is and what is wrong with my model?

Thanks!

Didn't get it to work with link180. the old version (link8) works though. strange but true
