Luc Scholtès posted a new comment:
I would just add that, as Bruno said, Nc>5 is not possible with DEM
using SPHERICAL particles. However, it is conceivable by using non
spherical particles (e.g clumps or polyhedra) as it is sometimes done
for modelling rocks. An alternative for that is to allow near neighbour
contacts (contact between non overlapping particles) using the
aabbEnlargeFactor and interactionDetectionFactor. It is working pretty
well as shown in [1].

The questions now are more about what mterial do you want to simulate?
Rock? Soil? And also why are you saying that there is a mismatch between
simulations and experiments? This could also be due to an inappropriate
contact law...
