What engine parameters are used to handle interactions...

Hi Christopher,
see [1] for the list of available IGeom functors (for combination of
different shapes). Sorry, if I am right, there is no box-facet interaction
available.
You could use a polyhedron instead of box.
cheers

Hi,

The right question is in fact : which "engine" (Ig functor would be more rigourous) is adapted to handle the interaction between a Facet and a Wall ? It is not a matter of a parameters of a given engine, but you need to pick up the right "engine".

For some years, class names in Yade are really helpful for that : you are looking to something named "Ig2_Facet_Wall_SomeIGeom". So :

- any Ig functor with "Sphere" in its name won't suit

- give a look at https://yade-dem.org/doc/yade.wrapper.html#igeomfunctor, and you will see that, unfortunately, the thing you're looking for does not exist at the moment... But Yade is open-source... ;-)

Thanks for your prompt answers. I will try using a polyhedron. Is there a built-in engine that allows polyhedron-wall interactions?

Thanks very much!
