Chareyre proposed the following answer:
Hi Mark,

VdW forces are not implemented but I see no big obstacle to implement them.
It is close to the capillary force problem
(https://yade-dem.org/wiki/CapillaryTriaxialTest) in the sense that you
have additional forces that act between distant grains.
I recommend doing that in a separate engine, so that VdW forces will not
depend on a specific contact law (then you can switch between all
existing contact laws, linear or non-linear elasticity, contact moments,
etc.)
