Luc Scholtès proposed the following answer:
Hi Janaka,

Sorry I can't help you concerning the error you get, but I am wondering, are
you trying to create a model with around 9e6 particles? From your message, I
came to this conclusion doing:

NbParticles=specimenVolume/spheresVolume=(100*100*200)/(1.333*pi*0.23)=9e6

If it is the case, it is normal that your simulation takes so long, and I
would recommend not to use so much particles. Usually, you can model a
granular material using around 10 000 particles. If it is not the case, just
forget what I say...

By the way, welcome to YADE community

Cheers

  Luc
