Molecular dynamics simulations use restart options of the kind
RESTART WAVEFUNCTION COORDINATES VELOCITIES. These are the minimal options
needed for a smooth continuation of a Car-Parrinello molecular dynamics
simulation. Use of the suboption ACCUMULATORS ensures that the calculated means
(e.g. temperature) are correct for the whole simulation, not just the current
run. If Nosé thermostats are used it is important also the restart the
thermostat variables. This is achieved by adding the corresponding keywords to
the RESTART (NOSEE, NOSEP, NOSEC).
