Bruno Chareyre proposed the following answer:
Hi,
I guess you want to simulate elastic waves or something, but as I was reading phase 2 I did not see anything special exerted on the boundaries. 
If you analyze velocities in a situation of static equilibrium, what you get is just some random noise. It is not deeply surprizing that random noise depends on timestep (and, basically, on anything else).
Did I miss something?
Bruno
