running sample made of clumps

Try this for clumps, it should work. If not, let me know!

# create a few clump configurations by hand
from yade import pack
c1=pack.SpherePack([((0,0,0),.5),((.5,0,0),.5),((0,.5,0),.3)])
c2=pack.SpherePack([((0,0,0),.5),((.7,0,0),.3),((.9,0,0),.2)])
sp=pack.SpherePack()
print 'Generated # of clumps:',sp.makeClumpCloud((0,0,0),(15,15,15),[c1,c2],periodic=False)
sp.toSimulation()

O.bodies.append(utils.wall(position=0,axis=2))

O.engines=[
 #SubdomainBalancer(),
 ForceResetter(),
 InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Wall_Aabb()]),
 InteractionLoop(
  [Ig2_Sphere_Sphere_ScGeom(),Ig2_Wall_Sphere_ScGeom()],
  [Ip2_FrictMat_FrictMat_FrictPhys()],
  [Law2_ScGeom_FrictPhys_CundallStrack()]
 ),
 NewtonIntegrator(damping=.4,gravity=(0,0,-100))
]
O.dt=.7*utils.PWaveTimeStep()
O.saveTmp()
O.step()

There are some examples with clumps.
