Thanks, Bruno. I take your advice and it actually worked excepted that
the porosity is slightly different from I want, probably because of the
rebound of the particles.

I have been thinking that the function 'pack.filterSpherePack' does
nothing but clip from the packing a sample using the predicate as
boundary. Therefore the stress state inside the predicate must be
uniform. Do you think in a geotextile bag the stress dis-uniformity in
soil is negligible? If taking that into account, how to adjust the
packing process?

It is getting beyond the scope of this topic. Sorry about that.
