I do agree that increasing the density uniformly of all particles has a null effect (strictly).
In this discussion I was guessing that "density scaling" was referring to Yade's NewtonIntegrator::densityScaling, which is a _differential_ scaling and this one should definitely help in some cases (there is even an example script about that called densityScaling.py IIRC).

Are you asking someone to explain dimensional analysis? Just found , which seems relevant.
