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
