Dear experts,

I´m trying to obtain the “exact” shape of a hanging cable under wind, ice, and self-weight loads: cable.gh (56.3 KB)

First, I tried to deform a straight line between the two fixed end points but the Analysis Th.II component crashes (you can check it by setting “Straight” in the input value list). However, I only obtain “feasible” results using catenary (or nurb) initial curves instead of a straight line (set “Catenary” or “Nurb” in the input value list).

Note that I´ve disabled Bending and Buckling using the corresponding inputs in Line to Beam and in Modify Element components as indicated elsewhere for modeling cables in Karamba.

Is this the adequate way to model a hanging cable in Karamba? Should I use some other kind of analysis type, e.g. Large Deformations?

Thanks in advance!
