Section 5.2
time-steps used for the collection of the histograms is stated. Then each function is given in turn.
For each function a header line states the atom type represented by the function. Then z, (z)
and n(z) are given in tabular form. Output is given from Z = [-L/2, L/2] where L is the length of
the MD cell in the Z direction and (z) is the mean number density. n(z) is the running integral
from -L/2 to z of (xy cell area)(s)ds. Note that a readable version of these data is provided by
the ZDNDAT file (below).

The REVCON File
This file is formatted and written by the subroutine revive. REVCON is the restart configuration
file. The file is written every ndump time steps in case of a system crash during execution and at
the termination of the job. A successful run of DL POLY 3 will always produce a REVCON file,
but a failed job may not produce the file if an insufficient number of timesteps have elapsed. ndump
is controlled by the directive dump in file CONTROL (see above) and listed as parameter ndump
in the setup module file (see Section
). The default value is ndump = 1000. REVCON is
identical in format to the CONFIG input file (see Section
). REVCON should be renamed
CONFIG to continue a simulation from one job to the next. This is done for you by the copy macro
supplied in the execute directory of DL POLY 3 .
5.2.5
The REVIVE File
This file is unformatted and written by the subroutine system revive. It contains the accumu-
lated statistical data. It is updated whenever the file REVCON is updated (see previous section).
REVIVE should be renamed REVOLD to continue a simulation from one job to the next. This is
done by the copy macro supplied in the execute directory of DL POLY 3 . In addition, to continue
a simulation from a previous job the restart keyword must be included in the CONTROL file.
The format of the REVIVE file is identical to the REVOLD file described in Section
5.2.6
The RDFDAT File
This is a formatted file containing em Radial Distribution Function (RDF) data. Its contents are
as follows:
record 1
cfgname
a72
configuration name
record 2
ntprdf
integer
number of different RDF pairs tabulated in file
mxgrdf
integer
number of grid points for each RDF pair
There follow the data for each individual RDF, i.e. ntprdf times. The data supplied are as follows:
first record
atname 1
a8
first atom name
atname 2
a8
second atom name
following records (mxgrdf records)
radius
real
interatomic distance (°
A)
g(r)
real
RDF at given radius
