Next: Manipulating Trajectories, Previous: Dynamics, Up: Energy Manipulations

The first part of CONGEN's output after a dynamics command lists
all of the options that apply to that part of the run. Then, any
information about velocity assignments (temperature changes) follows.
Any time the velocities are changed in an anisotropic way, the motion of
and about the center of mass will be stopped. This results in a printout
both before and after this operation of the ``DETAILS ABOUT CENTRE OF MASS`'.
Its position and velocity are output followed by the components
of the angular momentum. The last line gives the translation kinetic
energy of the system, and thus one should expect a drop in the total
energy and temperature of the system afterwards.

Non-bonded interaction and hydrogen bond updates will appear intermittently and are cleared labeled.

Every `NPRINT` steps, the total energy and various contributions
will be printed. This output is preceded by a title which gives the
correspondence of numbers to energy names. After `IPRFRQ` steps will
appear the averages and RMS fluctuations. After the second such printout
of averages and RMS fluctuations, the averages and RMS fluctuations for
the run up to the last turning of the molecule will be given. This gives
you longer range statistics. Such a calculation will not be done if
`IPRFRQ` equals `NTRFRQ`. The ratio of total energy to kinetic energy
fluctuations is an excellent measure of the accuracy of the run.

After the averages are printed, a least squares fit of the total
energy against the step number will be made to look for drift in the
energy. Two such values are printed, one for the last `IPRFRQ` steps, and
one to the previous turn. Next, the initial energy for the statistics,
both short range and long, are printed. Finally, the correlation
coefficient of the energy versus step is given for both ranges. A value
close to zero indicates no systematic drift; a magnitude near 1 means
you have a real problem with the dynamics.

This process of printout continues until the end of the run is reached. Just before the last energy is printed will appear a message about the writing of coordinates and velocities to their respective files.
