### fix_modify AtC filter

#### syntax

fix_modify AtC filter <on | off | equilibrate>

- on | off (keyword) = turns filter on or off
- equilibrate = runs dynamics without filtering but initializes filtered quantities

#### examples

`fix_modify atc transfer 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 be used with specific transfers: thermal, two_temperature

#### related

fix_modify AtC filter scale
fix_modify AtC equilibrium_start

#### default

off
