Karol Brzezinski posted a new comment: Hi Jan, thank you for this example. This can be a good starting point for playing with potential blocks. Right now, I am not able to run it because my version of Yade doesn't have 'misc.py' and 'PotentialBlock2AABB()'. If I knew it is the only problem, I would dig into the Potential Blocks, but I want to split those polyhedra later. Referring to the original problem of normal force direction, I think that I have a conceptual solution. I do not have any proof, it's kind of intuitive. In general, all the systems tend to have minimum energy. -> So the contact force should act in the direction that causes a certain force change (volume change) with minimum displacement. -> Movement should be perpendicular to 'the widest cross-section'. -> The projection of hull intersection on the sought plane (normal to the force) should give a polygon of the biggest area. Implementing it in Yade is out of my reach, but maybe I will test it in Python (for geometry from my example).
