Okay, I will be on that part soon :)

firstly, I am trying to fill in the created cylinder with spheres. I did the following (full script):
#  """creates cylinder made of boxes. Axis is parallel with z+""
from math import sin,cos

def cylSurf(center,radius,height,nSegments=12,thick=0,**kw):
  
   center = Vector3(center)
   angles = [i*2*pi/nSegments for i in range(nSegments)]
   pts = [center + Vector3(radius*cos(a),radius*sin(a),.5*height) for a in angles]
   ret = []
   for i,pt in enumerate(pts):
      l = pi*radius/nSegments
      es = (.5*thick,l,.5*height)
      ori = Quaternion((0,0,1),i*2*pi/nSegments)
      ret.append(box(pt,es,ori,**kw))
   return ret

surf = cylSurf((1,2,3),4,5,nSegments=12,thick=.1)
O.bodies.append(surf)

# create the lower plate
lower_plate=O.bodies.append(box((1,2,3),(4,4,0.0002)))

#pack the body (named "surf" with spherical particles)

sp=pack.randomDensePack(surf,radius=0.01,spheresInCell=300)
O.bodies.append(sp)
yade.qt.Controller()

This gives the following error:
File "/usr/bin/yade", line 182, in runScript
    execfile(script,globals())
  File "box-cylinder.py", line 19, in <module>
    sp=pack.randomDensePack(surf,radius=0.01,spheresInCell=300)
  File "/usr/lib/x86_64-linux-gnu/yade/py/yade/pack.py", line 418, in randomDensePack
    if not dim: dim=predicate.dim()
AttributeError: 'list' object has no attribute 'dim'

Is there another method to pack the body with a set of spheres?
