Question #229891 on Yade changed:
https://answers.launchpad.net/yade/+question/229891

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

for i in O.interactions:
  if not i.isReal: continue
  cp = i.geom.contactPoint # [1]
  fn = i.phys.normalForce # [2]
  fs = i.phys.shearForce # [3]
  # now do whatever you want with the values

please note that i.phys.someForce has the meaning of internal force, so for
each body the interaction connects the force acts with opposite sense.
