Question #261928 on Yade changed:
https://answers.launchpad.net/yade/+question/261928

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Behzad,

len(O.interactions) also consideres potential interactions (when bounding
boxes collides)

if you use "for i in O.interactions:", the iteration is done over only real
interactions.

so try "print len([i for i in O.interaction])" and it should give you
correct results

cheers
Jan
