wire simulation

Post by DeepBioSphere »

Hello,

I'd like to simulate a really stiff wire (approximately like the steel cables used in bicycle brakes). My approach was to use generic6DoF links, constraining every DoF except the x and y (=non-torsional) rotation DoFs. Unfortunately I could not set a combination of limits and physical parameters that produced a sufficient stiffness.

We found out that, if a joint got beyond the limit value, the limits code (which replaces the "stiffness" code) did not work in Bullet. As a result, the motion was completely constraint-less (no stiffness, but also no limit).

Is this issue known? - and can I do something about it?
Would the selection of some other link type solve the problem?

Best greetings, Michael
