<P>IMPORTANT NOTE: Excluding pairwise interactions will not work
correctly when also using a long-range solver via the
<A HREF = "kspace_style.html">kspace_style</A> command. LAMMPS will give a warning
to this effect. This is because the short-range pairwise interaction
needs to subtract off a term from the total energy for pairs whose
short-range interaction is excluded, to compensate for how the
long-range solver treats the interaction. This is done correctly for
pairwise interactions that are excluded (or weighted) via the
<A HREF = "special_bonds.html">special_bonds</A> command. But it is not done for
interactions that are excluded via these neigh_modify exclude options.
