Goodmorning,

I would like to ask some help on how to determine the shape of a filament with the two extremis held in place by a couple of mechanical joints. I would like moreover to export the obtained shape into a geometry that I can use in another simulation.

Thank you very much for the support. Cheers

Hello Pietro,

You seem to be describing a catenary problem. If so, the approach described in this blog post is what I would try.

Best,

Jeff
