Jan Stránský proposed the following answer:
Hello,
always try to read the very first problem/warning/error. In your case, the
output show
WARN yade/pkg/dem/Shop_01.cpp:423 PWaveTimeStep: PWaveTimeStep has not
found any suitable spherical body to calculate dt. dt is set to 1.0
so the time step is set to a very large value, making the simulation
unstable.
The solution is to set suitable time step manually or using
GlobalStiffnessTimeStepper (not sure if it works with polyhedra).
Also instead of clicking "play", you can try "step", which proceed only
one time step. It may (or not :-) reveal the problem better.
cheers
Jan
