Hi, I just started to get familiar with Yade. I'm trying to generate a random dense packing in a box with dimensions 2x1x1. By using randomDensePack function I get a packing fraction of approximately 0,3 which is not very good.

My packing parameters are

pred=pack.inAlignedBox((0,0,0),(2,1,1))

spheres=pack.randomDensePack(pred, radius=0.1, cropLayers=0, rRelFuzz=0.0, spheresInCell=2000, memoizeDb=None, useOBB=False, memoDbg=False, color=None, returnSpherePack=True)

It gives me coordinates for 147 spheres which gives a packing fraction of 0,31. Is there something I should modify in the parameters?

Thanks,
Oskari
