Question #293445 on Yade changed:
https://answers.launchpad.net/yade/+question/293445

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Mike,
according to PolyhedraVolumetricLaw (which was renamed to
Law2_PolyhedraGeom_PolyhedraPhys_Volumetric), it seems you have an older
version of Yade. Since then, there were some changes in polyhedra code. Is
it possible for you to try the script with some newer version?
cheers
Jan
