    Status: Open => Answered

Jérôme Duriez proposed the following answer:
O.engines does not tell much in itself here. Particle size
considerations are at least as much important: with "big" particles, the
behavior is anyway insensitive to capillary forces, and I would expect
the same result between (dry), (use of
Law2_ScGeom_CapillaryPhys_Capillarity with uc1), or (use of
Law2_ScGeom_CapillaryPhys_Capillarity with uc2 > uc1)

Regarding your workflow and the sudden activation of capillary forces:
usually when you introduce new forces in a discrete system, things can
happen (e.g. contacts may create).

As for the "need of fcap calculation",
Law2_ScGeom_CapillaryPhys_Capillarity() computes and applies capillary
forces at capillary-bonded interactions each time the engine is executed
(at each DEM iteration, by default). Not sure I understood what you mean
here, actually.

PS : Your reference [*] in #2 can not be the same as mine in #1, it does
not help the discussion ;-)
