dielectric command
Syntax
dielectric value
value = dielectric constant
Examples
dielectric 2.0
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 command for more details.
Restrictions
none
Default
dielectric 1.0
