this export spheres at the time when python evaluates it. So probably
the line is "misplaced" in the code you are using.

Hello,
I have an additional question about saving of simulation results. So I
generate spheres in a cube and then apply the gravity. How can I save
the positions of my spheres after applying the gravity. In the graphic
window I saw that the gravity was applied, but my saved text file gives
me only the positions of spheres before gravity applying. I used
Oedometric test section of https://yade-dem.org/doc/tutorial-
examples.html. Can you please tell me how to save the position of
spheres after gravity in the given example code.
I used this command: file = export.text('test.txt',mask=-1).
Best wishes
Milly

Hello Jan,
I have one more question about saving the text file. I tried to do it,
but this command saves all spheres generated in the box. But I want to
save the positions only of spheres in my cylinder ('pred' in the code
above). The command that I usually use in python does not work here.
Should I maybe change something in the 'mask' parameter in
yade.export.text(filename, mask=-1)?
Best regards
Milly

Question #694102 on Yade changed: https://answers.launchpad.net/yade/+question/694102 Milly Ro posted a new comment: Hello Jerome, sorry for the delay. My question was not about the saving of the state of simulation, but about the saving of the positions of all generated spheres as text data without running (3D) simulation in the graphics window. So I have the following Python code for packing spheres in cylinder: sp0=pack.SpherePack(); sp0.makeCloud((-20,-5,-20),(20,5,20),psdSizes=psdSizes,psdCumm=psdCumm, rRelFuzz=.65, distributeMass=False) pred = pack.inCylinder((0,-5,0),(0,5,0),radius=25) for c,r in sp0: if pred(c,r): O.bodies.append(sphere(c,r)) My questions are: 1. How can I save each positions and size of my spheres in cylinder as text file? 2. If I write in makeCloud the values for psdSize and psdCumm, will an additional parameter 'rRelFuzz' be taken into account? Or it will be ignored because the particle distribution is known? I hope you understand what I mean :) Kind regards, Milly -- 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

[Yade-users] [Question #694102]: Save the simulation result without OpenGL GLX
New question #694102 on Yade: https://answers.launchpad.net/yade/+question/694102 Hello, I have the following question: how can I save my simulation result (for examply for script pack_cloud.py from GitLab https://gitlab.com/yade-dev/trunk/-/blob/master/examples/test/pack-cloud.py but with my own particle distribution) without graphics drivers. It seems that the server I am usig for YADE does not have the necessary graphics driver, because I have got the error "OpenGL GLX extension not supported by display". Since I do not have administrator rights, I cannot install anything myself. Actually I do not need the graphic representation of my simulation, but only the result/calculation. P.S. I am working on Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-178-generic x86_64) and my YADE version is 1.20.0.
