# 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.

none

## Default

dielectric 1.0
