Question #201064 on Yade changed: https://answers.launchpad.net/yade/+question/201064
jduriez proposed the following answer: Hello Mukesh, Nice "Yade exercise" ;-) Your results are consistent with the way Yade computes things (see http://bazaar.launchpad.net/~yade- dev/yade/trunk/view/head:/pkg/dem/NewtonIntegrator.cpp, or documentation surely) E.g, you have indeed : position(t=0.4) = position(t=0.3) + speed(t=0.4) * 0.1, and so on for other times (velocities are computed first, before modifiying positions) In my opinion, the discrete (in time !) feature of this integration scheme is the only reason why you do not get the exact solution. Try with smaller dt, and you should certainly approach the result you expect. -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
