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 :doc:`pair_style <pair_style>` command for more
|
|
details.
