    Status: Open => Answered

Jérôme Duriez proposed the following answer:
Hi,

Flow.ids is never used by the code of FlowEngine (see source code at [*]
if you wish to check it) so, again, it is *not a problem* if it is
neither defined by the user, nor updated by YADE itself ;-)

As for vizualizing movements, seeing with naked-eye particle movements on YADE GUI, or real-simulation time Paraview animations, is quite rare. (would you see sand grain movements during a triaxial test in the lab ?)
As such, this is not a good indicator whether things go "well" or not.

Jérôme
