  Different schemes for the treatment of long-ranged electrostatic interactions
will be examined for water simulations using the polarizable fluctuating charge
potential. Several different methods are compared, including Ewald sums,
potential shifting, spherical truncation and reaction field corrections. For
liquid water, properties such as the energy, pressure, dynamics and structure
are more sensitive to the treatment of the long-ranged interactions with
polarizable than with non-polarizable potentials.
