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.

Regards

Anton

Jonathan Pergoli confirmed that the question is solved:
Now I can distinguish between interactions:

def rollingfriction():
for i in sphere:
try:
O.interactions[m,sphere[i]].phys.kr=.15
print "Interaction between",m,sphere[i]
except:
print "No interaction exists",m,sphere[i]

Thank you guys for helping me. :)

[Yade-users] [Question #293635]: Problem with visualization of boxes in ParaView 4.0.1

2016-05-12 Thread Jonathan Pergoli 
New question #293635 on Yade:
https://answers.launchpad.net/yade/+question/293635

Hi everybodi!

I cannot see rotation of my box when I postprocess it with paraview. 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?

Thanks

Status: Needs information => Answered

Jan Stránský proposed the following answer:
Hi Mike,
using pure yade, it resulted in segmentation fault in my case.

However, I noticed that the polyhedrons are really "crazy", completely
intersecting each other. I think in this case the DEM itself is not valid
anyway.. Is this a script just to reproduced the problem, or are you using
the script in other situations?

from my point of view, periodic boundary is just the opposite faces of
periodic cell

Both of topics above, what is mean of use these concept on the
simulation?


from reading the table of contents of the book you mentioned, it should be
clear from the book :-)

Will it have to save time on the simulation?


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
