VG is still having a problem:
Hello everyone,
I have another follow up question: The packing generated using
TriaxialStressController in compress.py
(https://github.com/yade/trunk/tree/master/examples/agglomerate) is not
stable in the presence of gravity. In other words, when I load this
packing in simulation.py and run the simulation only with gravitational
forces, the particles move quite a bit. Is there a way to make this
packing also stable in the presence of gravity.
I am trying to follow the solution proposed by Bruno here, but not quite sure
how it works: https://answers.launchpad.net/yade/+question/263739
In this case, should I just run it first for few iterations with gravity and
then set the triax.goal as suggested.
Also, in the compress.py, is it not necessary to get unbalancedForce() below
some threshold value ? I tried to put a threshold, but with the given
parameters of triax.goal = -1e-5, the unbalancedForce() does not come down.
However, if I use, triax.goal = -10000, then it comes down below 0.01 within
few iterations.
Thanks
Varun
