Jan Stránský proposed the following answer:
Hello,
apart from the warnings, you also have one error:
FATAL /build/yade-fDuCoe/yade-2018.02b/pkg/common/InteractionLoop.cpp:143
action: None of given Law2 functors can handle interaction #70+76, types
geom:ScGeom=1 and phys:PolyhedraPhys=16 (LawDispatcher::getFunctor2D returned
empty functor)
you have created ScGeom from Polyhedra-Polyhedra contact, PolyhedraPhys from
PolyhedraMat-PolyhedraMat contact, but you have no law combining ScGeom and
PolyhedraPhys...
Use Ig2_Polyhedra_Polyhedra_PolyhedraGeom() instead of
Ig2_Polyhedra_Polyhedra_ScGeom()
Apart from that, set a suitable initial time step as
GlobalStiffnessTimeStepper(defaultDt=0.001), # 0.01 is an example
With no hint, GlobalStiffnessTimeStepper has no idea what to choose and set dt
to 1, which leads that after the very first time step, the polyhedrons are far
below the main scene..
cheers
Jan
