I attached a script to reproduce the bug, when fusionDetection=True and
hertz model is used. The bug occurs, when contacts are created. In the
script I created two fixed particles and one

Thanks for the input.
I see that, at iterations 2049-2050 (when the mensci are created), the
displacement of the particle is very high and lead to overlaps of about 50%.
This is apparently what causes the crash. With higher shear modulus the problem
disappears, since the capillary force no
Anton, Christian,
I just realized that I should have accepted the pending merge request in
git interface already.
There are so many screens and links there that I'm still a bit lost...
I start to see the improvement in the branching easyness of git,
allthough is a bit harder to keep track of
Thank you for your comment. If I set a higher shear modulus (1e6 instead
of 1e5) this script does not crash, but in my other model I use 3e7 and
it crashes too, when it gets dynamic. First I will increase shear
modulus also for this model, but later it should be fixed.
Does anyone has an idea how

Oh, I thought I am the only one, who feels like that
I will think about it. Not sure when I will come up with a solution.
Clearly in the example you sent the bug surface because capillaryForce

mean, capillary forces will never generate 50% overlap). I hope the
problem is similar in
Hi Boon,
It may be due to the fact that the DEM is a numerical method: at each
time step particle velocities and positions are deduced from a numerical
integration of Newton's law. This numerical integration is based on
finite differences which accuracy depends on the size of the time step.

Hi all,
To Christian: I have understood the following. When you want to do a
pull request, choose only the commit, you want to be merged. No need
to choose all commits of your local branch to escape confusing. In
this case pull request works just fine.
To Bruno: could you, please, setup your
