Question #293576 on Yade changed: https://answers.launchpad.net/yade/+question/293576 Status: Answered => Solved Raphaël Maurin confirmed that the question is solved: Hi Anton, Sorry I was not clear, I didn't recompile libqglviewer, I just installed it. For the installation of Yade, you were right, the problem was standing in the fact I didn't have the package pyqt5-dev-tools. I recompiled Yade and everything is fine, it is running. Thanks !

Question #293576 on Yade changed: https://answers.launchpad.net/yade/+question/293576 Status: Open => Answered Anton Gladky proposed the following answer: Hi Rafael, first of all, I do not clearly understand, whether you recompiled libqglviewer or not. You do not need to do it. Just install libqglviewer-dev from standard repository. An error, which you refer just means that you probably missed python-pyqt5 or pyqt5-dev-tools. Please install them and try again.

If I open the contreller I can see the box star rotating after bouncing on the ground, but when I open it with paraview I the box is always in horizontal position. The problem is that I cannot use SnapshotEngine because I have to run my simuations on vesion without the graphic interface. Can someone help me?

To save simulation time is usual reason of its usage, to simulate just part of the domain if you know / assume that the rest of the domain behaves periodically. But it does not "have to save time on the simulation" What will it be the difference when i am using these concepts or not? The main difference is that with periodic boundary conditions the simulation is periodic, and vice versa :-) with all advantages and disadvantages You may check this example for instance [1] or try the following simple script showing interactions of three particles crossing the periodic boundaries cheers Jan O.periodic = True O.cell.setBox(6,10,14) b1 = sphere((0,0,0),1,color=(1,0,0)) b2 = sphere((2,4,4),1,color=(0,1,0)) b3 = sphere((4,8,8),1,color=(0,1,1)) O.bodies.append((b1,b2,b3)) O.step() b3.state.vel = 5e-5*Vector3(-1.1,-2,-2.2) # from yade import qt qt.View() O.run() [1] https://www.yade-dem.org/wiki/Miscellaneous_videos 2016-05-12 0:12 GMT+02:00 Felipe : > New question #293600 on Yade: > https://answers.launchpad.net/yade/+question/293600 > > Hello Everybody, > > I would like to know how i can get more information about periodic cell > and also periodic boundary. > > I have studied about this topic with the help of Sullivan - Particulate > Discrete Element Modelling book and others paper wich focus on interaction > between the spheres. > > Moreover, I was seeing on DEM Background (YADE) if i would get more > information but I did not understand how i can use this concept on the > simulations. > > By the way, I have been asking in this question if it would be possible to > explain with more details how to use: > > -> Periodic Cell; > > -> Periodic Boundary; > > Both of topics above, what is mean of use these concept on the simulation? > Will it have to save time on the simulation?
