Hi everyone, I'm new at YADE.
I am trying to simulate uniaxial compression. I have a rigid cylinder filled with particles and then I'm using rigid plane to perform compression. My goal is to get the goal distribution along the z-axis of the cylinder. I was planning to obtain all particles that are in contact with the cylinder wall and then extract their positions and forces in .txt file and then somehow get the load distribution. Can anyone help me with the part where i need to find IDs of particles that are in contact with the wall? Or, even better, are there any more simple solutions for this? 
Thanks in advance!

Definition of cylinder walls and particle filling:
O.bodies.append(geom.facetCylinder((a/2,a/2,3*b/2), a,3*b, wallMask=6))
sp = pack.SpherePack()
sp.makeCloud((0, 0, 0), (0.03, 0.03, 8*b/3), rMean=rMean, rRelFuzz=rRelFuzz)
sp.toSimulation(material='spheres')
