Hi,
I am trying to use makeClumpCloud to generate a volume filled with clumps. Even though the volume is quite large, the number of clumps added to the packing is quite limited (see image: http://pasteall.org/pic/485b8c6d558fcbecc33cf58cf7b74e00) and I receive the warning
"Exceeded 200 attempts to place non-overlapping clump. Only 12 clumps were added, although you requested 100" 

Does anyone know why yade is unable to add more clumps to the simulation?

Many thanks
Jesse

maxCorner = (5e-7,5e-7,5e-7)

#O.periodic=True

# load clumps
ymport.textClumps('/tmp/clump0.txt')

c0 = pack.SpherePack()
c0.fromSimulation()

O.resetThisScene()

#c1 = getClumpInfo()
c1 = pack.SpherePack()
c1.fromSimulation()

O.switchScene(); O.resetThisScene()

print('Creating Clump Cloud')

test = sp.makeClumpCloud(minCorner, maxCorner, [c0,c1], periodic=True, num = 100)#, periodic=True, num=-1, seed=1)
#test = sp.makeClumpCloud(minCorner, maxCorner, [c0,c1], periodic=True, num = 1000)#, periodic=True, num=-1, seed=1)

sp.toSimulation()
