do you mean something like this, using ForceContainer [1]? for b in O.bodies: f = O.forces.f(b.id) t = O.forces.t(b.id) doWhatewerWith_f_and_t()
As I understand the documentation (did not use ForceRecorder myself), totalForce is really the total force, i.e. sum of all forces acting on engine's ids). So, as I understand your question, I would prefer to use ForceContainer cheers Jan [1] https://yade-dem.org/doc/yade.wrapper.html#forcecontainer 2015-06-24 11:46 GMT+02:00 Fu zuoguang <[email protected] >: > Question #268448 on Yade changed: > https://answers.launchpad.net/yade/+question/268448 > > Status: Answered => Open > > Fu zuoguang is still having a problem: > Dear Jan Stránský and all users, > > I am sorry for giving you an ambiguous description of my purpose. > > ################################### > > for b in O.bodies: > O.engines.Recorder.ForceRecorder[body_id = b].totalForce > O.engines.Recorder.TorqueRecorder[body_id = b].totalTorque > > ################################### > > The codes that I provided yesterday are not the true python codes but > the pseudo codes that just helps me express logically my desirability. > Of course, These sentences should not be validated by python.(exsit errors) > But they are not very clear for understanding.
