effective wiggling

Submitted by knoe_ph on Fri, 06/29/2012 - 13:37

Hi everybody,

I'm looking for an effetive way of wiggling a pebble bed in order to reach a high packing factor.

When using the "fix_move wiggle" command I need to set the amplitude vector and the period of oscillation.
I'm not sure which values are best for effective wiggling? Right now I'm using an amplitude of about 1/10 particle diameter and an oscillation time of 0.0005, but my results are quite unsatisfying.

Do I have to follow a specific correlation between particle diameter and wiggling amplitude or oscillation time for best results? Maybe someone more experienced can help me with that.

Kind regards,
Philipp
