Question #153493 on Yade changed:
https://answers.launchpad.net/yade/+question/153493

Anton Gladky proposed the following answer:
I think the problem in your code is in indention. It should look like
this:

def addPlotData():
  plot.addData(i=O.iter,unbalanced=utils.unbalancedForce(),**O.energy)

and

def checkUnbalanced():
  if utils.unbalancedForce()<.05:
  O.pause()
  plot.saveDataTxt('bbb.txt.bz2')
