I've got other 2 questions: setting Young modulus low to 10^3 what
implies, it act on Kn right?
Yes.
If you use my definition of Kn (i.e. "SimpleElasticRelationship"), Kn is
proportional to (Young modulus x diameter). That way, you get a constant
macro-stiffness for a packing whatever the particle size.
