Re: [Question #705955]: MindlinDeresiewitz Contact Law Issue


Question #705955 on Yade changed:

    Status: Open => Answered

Bruno Chareyre proposed the following answer:

> Has the contact law been tested before?

I am not quite sure.
Maybe Chiara Modenese used mainly one of the different versions in here PhD although she implemented all of them. So it is not extremely surprising if they have different levels of maturity.

Maybe you found a bug.

What's surprising is that contact detection is not so much dependent of
the Law2 functors. If you could reduce the example script to a simpler
case it would help finding out if it is really a detection problem, as
you suspect, or something else. I mean: reduce the number of PyRunners,
impose velocity instead of exerted force, and show that a contact should
exist after (let's say) 10 iterations.

In any case, I strongly recommend that you go through code-inspection
and, at least, basic verifications of the results if using that functor
(of course, that's if at least something is computed...).
