Dear All,
hello.

In granular mode, we need to know the information of all contacts. I mean we need to know the position of each contact, and also the indices of the two particles in that contact and the force between them. Is it possible to save the information of the all contacts in a file?

Kind regards,
Mehdi

That info is stored within LAMMPS (see the pair granular routines),
but there isn't any automatic way to dump it out, without adding some
code to do it. You could instrument one of the pair routines
to do it.
