[Tabulation]
section¶
This section defines the file format in which potable
will write its output files through the target configuration item.

- Input format reference: [Tabulation].
The pair-tabulation target can be one of:
DL_POLY
(orDLPOLY
): this creates output in theTABLE
format accepted by theDL_POLY
simulation code.LAMMPS
: creates output suitable for use with the LAMMPSpair_style table
(see Using Basak.lmptab in LAMMPS).GULP
produces a table for theGULP
code by defining a set of separation, energy pairs using theGULP
spline
directive.
Defining table cut-off¶
The extent of the table is defined in the [Tabulation]
section using the nr, dr and cutoff options:
dr
defines the row increment (step-size) between table rows.cutoff
gives the maximum separation to be tabulated.nr
determines the number of rows in the tabulation.
Any two of nr
, dr
and cutoff
can be used to define the extent and resolution of the tabulation. As an example all three of the following [Tabulation]
sections would produce a table with 1000 rows, each separated by 0.01:
cutoff
andnr
[Tabulation] target: LAMMPS cutoff : 9.99 nr : 1000
cutoff
anddr
[Tabulation] target: LAMMPS cutoff : 9.99 dr : 0.01
nr
anddr
[Tabulation] target: LAMMPS nr : 1000 dr : 0.01
