Question #702665 on Yade changed:

Karol Brzezinski proposed the following answer:
Hi,

Yes, first you generate facets, next particles. I only meant that
facetbox() function creates facets, not particles (as stated in the
first post).

Referring to your question, this is how you can obtain the height of spherical particle packing:
#################
O.bodies.append(geom.facetBox((0.05, 3, 4), (0.1, 3, 4), wallMask=63))
sp = pack.SpherePack()
sp.makeCloud(Vector3(0.05,0,0),Vector3(0.05,6,8), rMean=0.05, rRelFuzz=0)
sp.toSimulation()
O.engines[4].gravity = (0,0,-10)
O.run(3000,True)

(xmin,ymin,zmin),(xmax,ymax,zmax) = aabbExtrema() # you can use aabbDim() instead in those two lines if you only need height
height = zmax-zmin
print("Height is ",height) 
################

Cheers,
Karol
