Bruno Chareyre posted a new comment: Hi, Using the position of the wall instead of the contact point is perfectly fine. The sum of f*l really runs over all interacting pairs regardless of the shapes of the objects. The nice thing with this expression is it doesn't require the notion of a "contact point", at all. Which is great when the interactions are remote (capillary forces, electrostatic, lubrication, etc.). In general it would be wrong to select different reference points for one single object when defining "l". It is correct in the particular case of an external wall, though. And therefore the suggestion by Jan and Jerome are correct too (at least for those interaction models which define a contact point, not always the case). It gives the same result in practice.
