cable net link 180 with out of plane load

      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!
