The velocity-rescaling option (IEQFrq not zero) periodically rescales the velocities. It uses the equations

where
**n**
is the number of free atoms in the system,
is Boltzmann's constant,
is the temperature in K specified by
the FINAltemperature parameter, denotes
the velocity of atom **i** at
time **t**, and angle brackets enclose a trajectory average over the time intervals
between the rescalings.
