Good to hear!
Thank you for reporting, it made me spot the problem with clump.

Just need to test it a little more, compare results etc.
Also we need to think about jumping spheres problem. For example, we
could create one more container in the scene, for example, where will
be pointers on just created spheres... Anyway, I need to have a

Very good. :)
I was not sure it would improve in such granular flow case (my mind
was more on quasi-static situations when working on that).

Remember there is a wiki page to report results. I'm stilll
Hi,
Thanks for the script Anton. This is what I found:
- A crash sometimes (not very often) occurs in GLrender(), it is
apparently due to deleted body. i could reproduce it before and after
bzr3001. I never crashed without opening the GL view.
- There was a typo in the modified probe(), it is

script and I'm still investigating).
It is not related to the new Newton::gravity, it only revealed another
bug in eigen's quaternions.
In your script, Klaus, the clump sometimes disappear, did you notice? It
is because the

I know about the problem with OpenGL-crashes. But for working
simulations I do not use

Please, have a look.
Ok, I was suspecting that to. I don't know why it happens precisely

Try 3009 please.

- One problem in your script it there are no spheres at startup, hence the
collider can't determine a verletDist and then it runs at each iteration,
which take a lot of time. I got a significant speedup by setting verletDist
explicitely to something positive (e.g. 0.002). I added a message
Hi Bruno,
thanks for having a look at my scripts!
I know that the clump is disappearing sometimes on the display but the
simulation itself seems to be ok so I never had a closer look at it. But it
was good you did ;-)
I just had a look at rev 3010 and now I got some speed up too which is
Hi, Bruno,
I have prepared a small test-script from examples/packs.py. It is
similar to one, which is crashes in my case,I could not catch a
crash with this test-script, but it seems, BoxFactory creates new
spheres not in the right places:some of particles are jumping, it
can be caused by the
the bottleneck is SpheresFactory which is working with new version
incorrectly and
cannot find places for new bodies.
I think I see the problem. Since you are using bounding boxes for
finding places, you have problems with the default Verlet distance (0.7
* mean_radius).
Your algorithm is

Ok, I have got a segmentation fault.
Will try to prepare a simple test-script.
