Hi Luc,

you are right, I should have specified I was looking for an isotropic sample
more or less. But in fact you also remind me another related point I perhaps
guessed in the past. Can we visualize the distribution of contact force say
with thicker/thinner arrays according to the intensity of the force? How?
