Expose particle-wall contact data in compute pair/gran/local?

Hi all,

I am using compute pair/gran/local and the corresponding dump to look at the particle-particle contact data (and heat flow), but also need to look at particle-wall interactions. As far as I can see, these are not included in these computes/dumps?

I think this would be a very useful addition - I guess it would require assigning each wall an ID etc. In particular I need to identify particles in contact with the wall, and sum their heat fluxes etc.

In the meantime, is there another way of identifying which particles are in contact with a given wall at a particular timestep? I was planning to use the wall/particle contact from the dump local, hence this question... but for now any method would be good :)

Thanks!

Mark
