Question #677362 on Yade changed:
https://answers.launchpad.net/yade/+question/677362

Robert Caulk proposed the following answer:
>>I tried randomDensePack for a cylinder but it only give a porosity of
about .65 while I need porosity~.2-.3

randomDensePack is not currently capable of returning a packing with a
desired porosity.

>>Can you please help with that.

Following the method shown in [1], your code might want to look
something like this:

## porosity reached above## 
pred =pack.inCylinder((.05,.05,.05),(.15,.15,.2),.02)
sp=SpherePack()
sp.fromSimulation()
O.switchScene()
spFiltered = filterSpherePack(pred,sp,material=material,returnSpherePack=returnSpherePack)
spFiltered.toSimulation()
export.textExt('name.spheres','x_y_z_r')
