Available Thermostats

The key Thermostat allows to specify the use of a thermostat during the simulation. Depending on the selected thermostat type, different additional options may be needed to characterize the specific thermostat behavior. At the moment, the following choices for the type parameter are available

None

No thermostat applied. This is the default if no Thermostat key is present.

Scale

Applies a scaling of the velocities in agreement to the specified temperature. The following options are required for this thermostat

frequency=NSteps

This parameter is optional. If specified, the thermostat will be applied every NSteps, using that step's ensemble temperature and the specified thermostat temperature to compute the scaling factor. If not specified, the thermostat will be applied at every step, using the mean temperature of the ensemble and the specified thermostat temperature to compute the scaling factor.

temperature=Temp

Specifies the temperature of the thermostat, in kelvin. This parameter is mandatory.

Berendsen

Applies the Berendsen thermostat. The following options are required for this thermostat

tau

Specifies the initial tau parameter for the Berendsen thermostat, in femtoseconds (can be changed via Units key).

apply=local|global

Defines the scope of application of the scaling correction, either per-atom-velocity (option local) or on the molecular system as a whole (option global)

temperature=Temp

Specifies the temperature of the thermostat, in kelvin. This parameter is mandatory.
