Jan Stránský proposed the following answer:
Hello,

> Can I do it through the boolean operation between polyhedra?

no:
- polyhedrons in Yade are convex
- no boolean operations are implemented anyway

If you need the cylinder to be dynamic, you can clump several
polyhedrons / boxes / facets / pfacets / whatever shapes to form desired
hollow cylinder and set desired dynamic properties (mass, inertia).

If the cylinder is just fixed boundary, you can simply made if from
fixed facets (or any other fixed shapes).

cheers
Jan
