NHC_PERIOD

From VASP Wiki

NHC_PERIOD = [real]
Default: NHC_PERIOD = 40 

Description: Time scale of the Nosé-Hoover chain in terms of the number of MD steps.


NHC_PERIOD sets the time scale () of the Nosé-Hoover–chain thermostat NHC_thermostat. It is expressed in terms of the number of MD steps and must be interpreted in combination with the time step set by POTIM. The setting NHC_PERIOD=0 corresponds will generate the NVE ensemble.

Tip: The value of NHC_PERIOD should correspond to a characteristic time scale in the system. If this is unknown, NHC_PERIOD should be set to a value between 20 and 200.
