Thank you, Jan.

> you use the same young? then what are the differences in both approaches? Answering it should significantly help.
Actually I don't use "young" with the ViscElMat as I mentioned in the code. Let me copy that here:

O.materials.append(ViscElMat(kn=Kn,ks=Kt,cn=0.0,cs=0.0,density=particleDensity,frictionAngle=radians(compFricDegree),label='spheres'))
O.materials.append(ViscElMat(kn=Kn*100,ks=Kt*100,cn=0.0,cs=0.0,density=0,frictionAngle=0,label='walls'))

I define these parameters and that is what I want as the input
parameters (Kn, Ks, Density, Friction).
