Microparameters of particles.

Kn	ks	μ	ρs	n	dp	r-max	r-min
3e6	3e6	0.1	2600	0.1	0.7	2.4	0.01

Note. kn is the normal stiffness (N/m); ks is the shear stiffness (N/m); µ is the friction coefficient; ρ_s is the density of particles (kg/m³); n is the porosity of the model sample; dp is the damp; r-max is the maximum diameter of particles (mm); r-min is the minimum diameter of particles (mm).
