# fix_modify AtC filter command

## Syntax

    fix_modify <AtC fixID> filter <on|off|equilibrate>

- AtC fixID = ID of fix atc instance

- filter = name of the AtC sub-command

- on or off or equilibrate = Select state of filter

## Examples

    fix_modify AtC filter on

## Description

Filters the MD dynamics to construct a more appropriate continuous field. Equilibrating first filters the time derivatives without changing the dynamics to provide a better initial condition to the filtered dynamics.

## Restrictions

Only for use with these specific transfers: thermal, two_temperature
