Thank you for your input!

@Jan: I was thinking of using a "facet", but I could not find a good
description of this type of geometry. For example, in the gravity
deposition example (https://yade-dem.org/doc/tutorial-examples.html) a
FacetBox is used that exhibits rigid-like boundaries. Would it be
possible to create a facet floor?

@Bruno: I am unable to get the desired result by increasing the Young
value.

This is what I currently have for the floor:

O.materials.append(FrictMat(density=1, young=1e15, poisson=0.3, frictionAngle=radians(30), label='boxMat'))
lowBox = box( center=(length/2.0,height/3.0-thickness/2.0,width/2.0),extents=(length,thickness,width),fixed=True,wire=False)
O.bodies.append(lowBox)

And for the particles:
O.materials.append(FrictMat(density=1000,young=1e4,poisson=0.3,frictionAngle=radians(30),label='sphereMat'))
sp=pack.SpherePack()
sp.makeCloud((0.0,height/3.0+thickness+mean+radius,0.0), (length,height,width),rMean=mean,rRelFuzz=radius,num=number,periodic=True)
O.bodies.append([sphere(s[0],s[1],color=(0.6+0.15*rand(),0.5+0.15*rand(),0.15+0.15*rand())) for s in sp])
