Re: [Question #689025]: Difference in unbalancedForce() between yade and yadedaily
Question #689025 on Yade changed:
https://answers.launchpad.net/yade/+question/689025
Status: Open => Answered
Jérôme Duriez proposed the following answer:
What do you observe for O.interactions.has(0,1) ?
True for yade 2018.02b and False for the more recent one ?
If yes, that is another illustration/confirmation of the fact that more
recent versions should hopefully be more correct.
Clump members are not supposed to interact with each other (at least in
modern design [*] but I do not think this has ever been otherwise ?) and
yade 2018.02b looks wrong in this sense.
