Question #176993 on Yade changed: https://answers.launchpad.net/yade/+question/176993
Jan Stránský proposed the following answer: Hi Ning, in r3023 it is possible to create and switch between more than one simulations. Use something like this sNum = O.addScene() O.switchToScene(sNum) note that all attributes genrated with O (O.bodies, O.interactions, O.time etc.) called after O.switchToScene will refer to current scene only. Perhaps you will need some (I hope not so much :-) time for testing and getting used to it. good luck Jan Jan Stránský píše v Po 06. 02. 2012 v 10:43 +0100: > Hi Ning, > > I was looking on the Omega class, and it should be no problem to modify > it to contain several scenes and the possibility to switch arbitrarily > between them, I try and test it and inform you about the progress :-) > > Jan > > > ceguo píše v Po 06. 02. 2012 v 09:30 +0000: > > Question #176993 on Yade changed: > > https://answers.launchpad.net/yade/+question/176993 > > > > Status: Answered => Open > > > > ceguo is still having a problem: > > Hi, > > > > I still need an answer in this question.
