Tina Asia is still having a problem:
Hi Jan,

Thanks for your patience, but I got an error by importing the *.stl file
generated by the above code. The error and my new code are as follows.

from yade import ymport
from yade import pack
from yade import qt

pred=O.bodies.append(ymport.stl('tina.stl'))
spheres=pack.randomDensePack(pred,radius=0.001,rRelFuzz=0.3,spheresInCell=500,color=(1,0,1))
O.bodies.append(spheres)

qt.View()
qt.Controller()

I got this error:

Besides, I also tried pack.inConvexPolyhedron (https://www.yade-
dem.org/doc/yade.pack.html?highlight=pack.in#yade.pack.inConvexPolyhedron)
to fill a polyhedron with many sub-particles, but this one got error
too:

This is my code:

from yade import polyhedra_utils

rock = PolyhedraMat()
rock.IsSplitable = True
rock.strength = 6e3

poly = polyhedra_utils.polyhedra(rock, size=(0.01,0.02,0.01), seed=1)
O.bodies.append(poly)

pred=pack.inConvexPolyhedron(poly)
aabb=pred.aabb()
dim0=aabb[1][0]-aabb[0][0]
spheres=O.bodies.append(pack.randomDensePack(pred,radius=0.001,rRelFuzz=0.3,spheresInCell=300))
O.bodies.append(spheres)

from yade import qt
qt.View()
qt.Controller()

and this is the error:
