Regarding Peri style

Hi,

I have tried LAMMPS example problem for peridynamics.

When I run the script, screen out put has shown Total # number of neighbors
and Ave neigh/atoms.

May I know how its calculate or on which basis its calculate the above.

Also, I was going through pair_style peri (Lammps documents). It is
mentioned in the document that "*These pair styles do not support mixing*" .

Does it mean that peri style can not use with other style (Using pair_style
hybrid command).

I have attached snapshot for the reference.

first available neighbor list on rank 0 after the last step.

no. mixing refers to using arithmetic or geometric averages to obtain
e.g epsilon and sigma for atoms of type i with atoms of type j from
the i vs. i and j vs. j interactions.
peridynamics has no per atom type parameters.

using pair style hybrid with peridynamics makes little sense anyway.
