Bruno Chareyre proposed the following answer:
Hi Adel,
If you know in advance L,W,H, porosity, and size distribution, then you can deduce the number of particles that will fit in the volume.
Let you generate this number.
Next step: reach the target porosity. Be it with the triaxial engine or by gravity deposition you can use the same technique: reduce contact friction until porosity=target (care to not ask an impossible value, the minimum porosity is what you get when friction=0).

Bruno
