never used the gengeo library, I am reading this line in sphinx
documentation:
"LSMGenGeo library allows to create pack of spheres with given [Rmin:Rmax]
with null stress inside the specimen"
Would this be an alternative to running the compaction phase of the triaxial
class fixing a very low confining pressure?
