algorithmic modeling for Rhino
Often when I'm trying create some model, i want to have rigid elements. But when i use very high stiffness springs (over 1e7 for example) model collapses. I've tried using small time steps an so on but it doesn't work. Is there a way to create very rigid frames without using springs or bend resistance (also doesn't work)? If not, will there be in the future?
It should be possible to simulate spring stiffnesses even over 1e7 if you make the timestep small enough.
(I'd suggest something like 2e-4). Of course smaller timestep means slower simulation. You can increase subiterations (to say 60) to counteract this a bit.
And yes, I am hard at work on some new techniques aiming to improve things so that significantly stiffer springs will be possible in Kangaroo while still keeping a reasonable simulation speed.
