I am trying to model a tensegrity roof in Karamba. In this tensegrity roof all elements should be in tension (BLUE) apart from the vertical struts (RED). Additionally, some elements should be prestressed (Orange).
However, when looking at the internal forces, most elements seem to be in compression (below a visualisation of the elements in compression); Thus the structure seems to be modelled as a truss instead of the cable structure it should be.(normal force<0)
My question, therefore, is how to model this as the cable structure it is supposed to be instead of this truss. I looked at several fora how to model cables and do not see how to solve this problem.
Thank you in advance!
(I tried ‘cleaning’ the model as much as possible by clustering unnecessary components)
