Hi,

I'm trying to fill a cylinder with a given psd. Does anyone know why I get the message:

AttributeError: 'NoneType' object has no attribute 'hSize'

when I run the following code?

from yade import pack
psdSizes,psdCumm=[.00475,.0095,.0191,.0254],[7.3,25.8,88.3,100]
pred=pack.inCylinder(centerBottom=(0,0,-.237),centerTop=(0,0,.237),radius=.25)
O.bodies.append(utils.geom.facetCylinder(center=(0,0,0),radius=.25,height=.474,wallMask=31))
sp0=pack.SpherePack()
sp0.particleSD2(radii=psdSizes,passing=psdCumm,periodic=True,numSph=1000)
sp0.toSimulation()

Thanks in advance.
