I'd be surprised to see the problem coming from Newton integrator. You remember there are pending bugs in sphere-facet code?

Ok, I met this problem at the end of February, that is why I had to switch to contact damping.

I will try to repeat tests and will notify you about results.

                I just wanted this article for "personal" use. I have
                some ideas in modifying NewtonIntegrator, as I had
                some problems with it on small velocities.

            What sort (of problems and ideas)?

        In dynamic simulations I see "hanging" particles.

    Hello Anton,
    could you say more about these "hanging" particles? It sounds non
    physical behavior. What are more or less the parameters you were
    using? Time step, particle size...
    Thanks, Chiara
