Jérôme Duriez proposed the following answer:
Hi,
It seems to me you did not correctly reflect the behavior of YADE's capillary model (Law2_ScGeom_CapillaryPhys_Capillarity) in your question. For strictly overlapping particles, capillary forces still exist (where did you see the contrary ?).
Maybe you were confused by the idea that this overlap is not taken into account during computation of capillary forces through solving Laplace-Young equation:
- in reality two liquid bridges between strictly overlapping or just touching particles would be different (even with the same suction, surface tension, contact angle and particles radii)
- nevertheless, YADE capillary model will give you the exact same bridges / capillary forces for these two cases
