Bruno Chareyre proposed the following answer:
>is it possible in yade to use non-smooth contacts?

No.

Changing the stiffness (your first case) can be done in different ways.
1/if you multiply stiffness by F, multiply gravity by F at the same time, keeping the equilibrium unchanged, then decrease gravity progressively (e.g. a few percent every N iterations)
2/ increase stiffness more progressively, which is nearly equivalent

"supposing that 1mm=1m" is helpless.
