Hi, Sorry for the brief hiatus from yade this past few weeks.
I've rerun the simulation, & the yade primary view clearly shows the particles behaving as expected, being transported by the archimedes screws within the casing to the paddle section. However, playing the *.vtk files in paraview still shows the same problem of particles "drifting" out of the geometry. I'm thinking its an issue with the visualisation in paraview rather than what the *.vtk files capture. The reason being that if the *.vtk files truly captured the wrong data, the drift should be consistent in a specific direction regardless of viewpoint, something clearly not the case where I observe the particles drifting off in random directions based on viewpoint in paraview. Thanks & Rgds, Ken ________________________________________ From: yade-users-bounces+ken_mendoza=ices.a-star.edu...@lists.launchpad.net [yade-users-bounces+ken_mendoza=ices.a-star.edu...@lists.launchpad.net] on behalf of Vaclav Smilauer [[email protected]] Sent: 15 September 2010 18:11 To: [email protected] Subject: Re: [Yade-users] Visualisation problem: particles "drifting off" while maintaining container volume > try to use glyphes, as here described > https://www.yade-dem.org/sphinx/user.html?highlight=glyph#loading-data-into-paraview Anton, I don't think that would help. The squares are rendered at the center of spheres; so if they are out of the extruder themselves, so will be the glyphs. Ken, I added the 'ascii' option to VTKRecorder in the last commit, so you can check "manually" whether the positions match. I tried something like this (past to the yade command-line) TriaxialTest().load(); O.run(200,True); VTKRecorder(fileName='aaa-',ascii=True)() which creates file with name aaa-spheres.200.vtu and in there you can check the coordinates (the position array has no name, it appears under <Points><DataArray type="float32" Name="Array 0x25a0980"...>. The first sphere is body #6, so the first 3 numbers in the file should match O.bodies[6].state.pos. You can try the same with your data, although any discrepancy would surprise me, since VTKRecorder directly uses positions in Body::state. Let us know what you find.
