Sorry I wrote the wrong code. I did this:

What about this:
gravel=FrictMat(density=1700,frictionAngle=.9188,label="gravel")
O.materials.append(gravel)
MLI=FrictMat(density=1280,frictionAngle=0.1489,label="MLI")

Hello,
You mix here "geometry" [1] and "physics" [2] of YADE interactions. In
order to describe interactions in DEM, you need to know:

I'm trying to simulate a box falling on a cylindrical pack of spheres. The
spheres have coefficient of restitution = .1 and the box has a COR = .6. For
the spheres I have used
