contactBreakingThreshold random behaviour

Hi, We are trying to force Bullet/PyBullet to consider adding contact constraints (we already changed the solver to create LCP) between objects with large distance between them. I changed this parameter (contactBreakingThreshold) and also this (ContactProcessingthreshold) but when we do this some of...

Pybullet rigid and multi body representation

Hi all, Does Pybullet only support the btmultibody architecture from Featherstone? Is there any parameter we can set that allow us to use the btrigidbody architecture? Another question does the MLCP equations will be different in both architectures (btrigidbody and btmultibody ) Thanks all for revie...

MLCP solver

Is there any approach I can do to force the bullet to create the MLCP each iteration even if there is no contact between the bodies?

Re: Complementarity problem and friction approximation in Bullet

Hi, I am running into the same problem trying to understand what is actually running in the bullet stimulator.
Have you found any answer yet?

Non-linear complementarity problem VS LCP

Hi all, I am new to the dynamics and simulation world and I have a question. Does bullet solve a non-linear complementarity problem using PGS or it converts it to an LCP and solve it? and if it's the second case can someone point me to some sources of how to achieve this and in which part of the cod...
