Question #670169 on Yade changed: https://answers.launchpad.net/yade/+question/670169
Bruno Chareyre posted a new comment: Let me amend the first part of #8 for future reference, else the post sounds self contradictory. #8 says: "if you don't want different results from two impact simulations, initialize them with the same deposited positions." That is, if you don't want to SEE that the results can be different, initialize with same positions. It will only work as long as everything, strictly all parameters, are the same, and if you don't run in parallel. If you change the last digit of something or if you run in parallel it is always random. Conclusion: it is useless to seek repeatability, since the corresponding result is not superior in any way to a randomized output. It is like claiming that a sensor is better than another because the measurement error of the former, though unknown, is always the same. What we want from a sensor is the error to be small, not to be repeatable (*). Bruno (*) An error here is what would remain after calibration. Forget "if it's repeatable it can be calibrated" since it would not help for the above problem - there is no way to calibrate. -- You received this question notification because your team yade-users 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
