Surface Colloid Electrostatic Interactions

Dear Steve, Users,

I wanted to study the interaction of colloidal particles with surfaces
interacting using electrostatics as well as van der Waals
interactions. I see that we can employ "Yukawa/colloid potential" with
"pair_style colloid" to study the colloidal systems. But these
interactions are only listed for particles with certain radii. If I
want to study particle-surface interactions, how can I proceed?

I also see that there is wall/colloid option to take care of van der
Waals interactions. Is it possible to incorporate electrostatics as
well (like low surface zeta-potentials, where exponential term only
has distance from the surface, z)?

Any help will be highly appreciated.

Best Regards and a very happy new year to you.

Such a term would have to be added to the fix wall/colloid
command.

Steve

Thanks Steve,
I will look into that. :slight_smile:
