Is the original example (somewhere in examples/clumps/) working in
multicore mode (I can not test right now)?

And I have another note: You do not need to set particle dimensions in
relRadList and relPosList. You can use any value for X in the following
code and the result should be the same, so why not use X=1?

relRadList1=[X,X]

relPosList1=[[-X,0,0],[X,0,0]] #(has the same effect as
[[X,0,0],[2*X,0,0]])

Title:
  Crash when Parallelization is used for O.bodies.replaceByClumps

Status in Yade:
  New

Bug description:
  The script crashes (Erreur de segmentation (core dumped) ) when I try
  use more than one core, at the line O.bodies.replaceByClumps.

  YADE version: the latest one complied from getHub trunk

  A simple script:

  # encoding: utf-8

  # Sphere package:

  sp1=pack.SpherePack()

  # Create the spheres of the package:
  sp1.makeCloud((0,0,0),(0.5,0.5,0.5),rMean=0.0075,rRelFuzz=0.33)

  # Send them to the simulation:
  sp1.toSimulation()

  # Replace spheres with clumps:
  templates= []

  relRadList1=[0.0075,0.0075]

  relPosList1=[[0.0075,0,0],[0.0075*2,0,0]]

  templates.append(clumpTemplate(relRadii=relRadList1,relPositions=relPosList1))

  clumpIds=O.bodies.replaceByClumps(templates,[1]) # THE SCRIPT CRASHES
  BECAUSE OF THIS LINE !
