Hello everybody. 
I am beginner in yade. 
I created a  specific aggregate grading with 'psdSizes  & psdCumm ' in ' makeCloud '.
Now I want to select two  specific  ranges of particles and replac them with two different Clumps.
It is  a part of my code                                                                                            ####product trash#####
a=[0,.005,.01,.015,.02,.025,.03,.035] 
b=[0,.005,.01,.015,.02,.025,.03,.035,.04,.045,.05,.055,.06,.065,.07,.075] 
c=[0,.005]
d=[]
for i in a:
	for j in b:
		for k in c:
			d.append((i,j,k))
for i in d:
	O.bodies.appendClumped([sphere((i),.005)])
######clump 1#####
clump=O.bodies.appendClumped([sphere((0,0,0),.002),sphere((.002,0,0),.002)])
#####aggregate#####
from yade import pack
sp=pack.SpherePack()
sp.makeCloud((0,0,0),(1,1,1),psdSizes=[.001,.002,.078,.08],psdCumm=[0,.07,.71,1])
sp.toSimulation()
######replace######
for b in O.bodies:
	if b.shape.radiuse>.078:
		pass
	else:
		#the particle should be replaced by clump1.                                                                                                                                                                                      ##################################                                                                         I do not use the 'clumpTemplate' and 'replaceByClumps' commands because these commands select a percentage of the particles randomly and do not take into account the grain size. As a result, they may replace particles of the wrong sizes with the clump we do not intend.
Please guide me in replace part.
