Karol Brzezinski proposed the following answer:
Hi William,

First of all I need to tell you how to slow down your simulation. In the
last line, you should change the timestep to be smaller than
PWaveTimeStep() (e.g. 0.8**PWaveTimeStep()). Otherwise, the simulation
will become unstable after the particles start to touch each other.

Secondly, you can decrease the young modulus of walls. Usually, a
modulus 10-20  times bigger than for spheres is enough to prevent
particle "leakage".

If applicable, you can try to scale up the particles.

BTW do you take advantage of multithread computing (by simply running
the simulation with -j parameter)?

Cheers,
Karol
