By no means I am advanced user of Grasshopper. Read few threads here which lead me to believe someone here could explain to me if I could use Grasshopper and kangaroo for below described analysis. Few threads here provided a script in which a steel wire catenary could be calculated. For case I was i…

Have you looked at the Catenary component? Its inputs don’t correspond to your parameters. [Catenary_2025Apr9a2] I used it to do this: [Catenary_2025Apr9a] Catenary_2025Apr9a.gh (13.9 KB) Explaining it is too much work :bangbang: :wink:

Hello Joseph, file attached in the OP. Thank you for the reminder, should have done it at the start.

Are you expecting the cable to slide on that highpoint or would it be two independent catenaries? Have you lookedd at this example yet? [image] Analysis of catenary Grasshopper catenary_units.gh (17.4 KB) Here’s an example of a 30m long 1cm diameter steel cable, hanging…

Thank you both for the replies @martinsiegrist This was exactly the post which made me start mine. I checked file linked in there. However there, cable is fully steel and it is expressed via Youngs modulus and cross section, and material density. In my case I do not have this input as my wire is ma…

[image] Cable_calcs: In your script i don’t see any mechanical properties I have as input That might be an important clue that two points and cable length are all that matters? It’s been a lifetime since I knew much about catenary curves. I worked on a line crew as a summer job in college a…

Hi Jospeh Indeed I think this will work for at least the part of determining how much length of wire is between the points, and then I can figure out the total weight and count the reactions at the ends, to get the tension I am seeking as on my first screenshot. I think I saw somewhere in K2engine…
