Chareyre proposed the following answer: Hi, You can impose the velocity of the piston as b.state.vel=(x,y,z) after setting b.state.blockedDOFs='xyzXYZ'. You then make it zero in the begining and change for something else at some point. TranslationEngine makes this simple thing excessively complex in my opinion. I would suggest to forget it (*). Bruno (*) and even to remove it from source code for its anti-didactic effect, to keep only truly involved helico-rotational motion engines present Le jeu. 26 juil. 2018 16:43, Jan Stránský < question671...@answers.launchpad.net> a écrit : > Question #671132 on Yade changed: > https://answers.launchpad.net/yade/+question/671132 > > Status: Open => Answered > > Jan Stránský proposed the following answer: > > I applied a engine for movement of particles caused by gravity > > yes, NewtonIntegrator(...,gravity=[0,0,-9.8]) does this > > > after that I want to compress particles by the piston > > your TranslationEngine is ok. > > There are several options how to make it work, e.g. I would add the > piston with TranslationEngine after gravity deposition ends. > > cheers > Jan > > -- > 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 : yade-users@lists.launchpad.net > Unsubscribe : https://launchpad.net/~yade-users > More help : https://help.launchpad.net/ListHelp > -- 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 : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
