Saving data at certain stresses

Asked by Sina Jafari

Dear all,
How can I save contact forces or any other data at CERTAIN STRESSES? for example I want to have some data ONLY at mean Stresses of 1,2,3 and 4 Mpa. I know how to save data using pyrunner engine but it can only be called at certain timesteps not certain pressures. This is so important to me because there is a lot of particles in my model and the output file is so confusing and hard to handle. I would be so grateful if you help me with this.
Regards

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
