The sequence above crashes because it is nonsense... It creates a preprocessor "tt" but no scene is loaded. Hence, getting volume of body 10 when there are no bodies accesses an array out of bounds...
I added a test on id, so that TW is nonsense-proof. If body id doesn't exists it returns 0.

  Yade [4]: TW.triangulate()
  Yade [5]: TW.computeVolumes()

  Sergei, did you use it again recently, so I could figure out when it started to crash?
  Note : MicroMacro is crashing as well.
