Question #172345 on Yade changed:
https://answers.launchpad.net/yade/+question/172345

    Status: Open => Answered

Chiara Modenese proposed the following answer:
Your previous results were very different from mine, that was not due to
numerical precision but I could not tell what it was (I also did compare the
output of your original script with another Yade user and more or less
results were the same although not exactly). Let's say that this is not the
best example to test but I get your same result now. Also to answer your
question, walls are treated like spheres in the calculation of CN.
