Question #702412 on Yade changed:
https://answers.launchpad.net/yade/+question/702412

    Status: Open => Answered

Bruno Chareyre proposed the following answer:
Hi,

If there are only two bodies O.forces.f(0) and O.interactions[0,1] should be the same.
Except that the first will not give an error when there is no interaction.

Alternatively, this boolean could help: 
O.interactions.has(0,1) 
Cheers
Bruno
