I use SpherePack.particleSD in order to reproduce a specific PSD given via
points (see attributes radii and passing in the code). I do not have the
need to fix the void ratio or the porosity, those would be the result of the
compaction phase (if you are running the triaxial test). I prefer to reason
in terms of relative density, as Bruno many times suggested.
As for the use of SpherePack.particleSD, I will see to commit a simple
script when am back to my office.
