Question #239685 on Yade changed:
https://answers.launchpad.net/yade/+question/239685

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Sina,

You can use PyRunner even for this reason:

def doOutput():
  stress = whateverCommand
  If stress>0.99*requiredStress and stress<1.01*requiredStress:
    someOutputCommand()

O.engines = [
  ...
  PyRunner(iterPeriod=1, command="doOutput()")
]

Cheers
Jan
