Question #434127 on Yade changed:
https://answers.launchpad.net/yade/+question/434127

Jan Stránský proposed the following answer:
Hi Alma,
in principle what you want is possible, but it needs some modifications,
namely:
- probably making each block a clump of a few polyhedrons
- using Ig2_Polyhedra_Polyhedra_PolyhedraGeomOrScGeom, allowing ScGeom for
cohesive bonds and PlyhedraGeom for broken contacts
I will try to create an example soon
cheers
Jan

> Polyhedra are clearly not the most used shape in DEM in general and YADE
> in particular, and they are included in YADE since October 2013, which
> is not so old, considering also the probably limited users number.
> Hence, it is indeed not surprising there is no example of this type of

> The possibilities using polyhedras with YADE are reflected by the names

> a very small minority include "PolyhedraGeom" in their names, with only
> one "Law2_PolyhedraGeom" which does not look like it suits your needs.

> Since you don't want to convert all your polyhedra to sphere collection
> just in order to have cohesion between them, it is probable you will
> have to code yourself a cohesive polyhedra interaction model.

> Good news: YADE is open-source !
