What is the current situation in Yade? Particles do not "hang" on
facets, or you are still implementing meshed surfaces?
Btw, I remember when I wrote a 2D equivalent ((*) more or less) of
facets, it needed a way to keep the history of contacts when they were
sliding or rolling from one facet to an edge, and from the edge to
another facet. Is there something like this with Yade's facets, or do we
create new interactions for each new pair? I never looked into that part
of the code.

It is a good software with high scalability. Mostly used for
geomechanical tasks by Brisbane University in Australia.
It uses MPI-schema, what is excellent for clusters.
Exceptionally for me, there are 1 bug
(https://bugs.launchpad.net/esys-particle/+bug/442881) and 1
unimplemented feature, which keep me out of using it.
Anyway, it is good when you have 2 or more opportunity to choose
between software.

But there are some bugs which are not allow me to use ESyS for
my tasks.
Could you tell more about the "bugs" in ESyS? I'm interested in that.
I feel like some codes are perfect on the paper but fail when
somebody wants to actually do something with them, partly due to
academic gaps or intrinsic differences between computer science /
engineering science, physics of particles / geomechanics, fluid
mechanics / solid mechanics, dynamic flow / quasi-static
deformation, etc.
In this perspective, Yade has the advantage of being developped by
people using it for research (balance that with drawbacks in terms
of developpement speed and consistency of the design). Two
exceptions are Olivier Galizzi and Alban Daumer.
