SoftBody behaviour with time increment and iteration number
Posted: Wed Aug 17, 2016 8:38 am
Hi all,
I'm simulating a rope (softbody) as an spring in an engineering project.
However, I found out that soft body (not even ropes, but patches) behave strangely with time step and iteration!
Ok, I understand that the behaviour should change when iteration number is changed, but it must converge to an stable behaviour.
When I change the iteration number from 10, 50, 100, 200, 400, 1000, each case have a unique behaviour which I cannot find any clue of "Convergence" of soft body behaviour!
The larger the iteration number is, the stiffer the soft body become. Is there any bug through the mathematical sweeping process of softbody?
And its the case with time increment as well.
Have you faced the same thing?
