dielectric command :h3

[Syntax:]

dielectric value :pre

value = dielectric constant :ul

[Examples:]

dielectric 2.0 :pre

[Description:]

Set the dielectric constant for Coulombic interactions (pairwise and
long-range) to this value.  The constant is unitless, since it is used
to reduce the strength of the interactions.  The value is used in the
denominator of the formulas for Coulombic interactions - e.g. a value
of 4.0 reduces the Coulombic interactions to 25% of their default
strength.  See the "pair_style"_pair_style.html command for more
details.

[Restrictions:] none
