fix_modify AtC filter <on | off | equilibrate> 
 fix_modify atc transfer filter on  
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
only for be used with specific transfers: thermal, two_temperature
