algorithmic modeling for Rhino
Do you mean, assign to the same curve a tension force and a compression force? Or assign one curve with a tension force and another curve wit a compression force?
Both are possible, but the first is maybe a strange way to assign a force (but who am i to judge), cause for instance, if you'd assign a stifness of -1 and a stiffnes of +1 to the same curve, both forces would balance each other out.
I would like to define two stiffnesses for one element. One for when it is under compression and one for when it is in tension.
Like a rope or a cable. It has for tension a certain stiffness, but for compression it has none.
Oke, I hope this is what you where looking for (see attachments).
This is nice. I'll experiment with it.
I think it is less convenient that an element should be devided. It would be easier if it would be one element.
