    Status: Open => Answered

Christian Jakob proposed the following answer:
I am not familiar with randomDensePack, but as the name indicates it
will generate a dense packing. So maybe particles are overlapping and
high forces will act on particles. If time step is too high particles
can penetrate through walls (facets).

If you want to calm your model down to adequate velocities you may also
consider calm() function [1] in combination with a PyRunner[2]. An
example can be found here:
