PREDOM: Predominance Area Diagrams
Format of the Input Data-File
Format of Input Data-Files:
Input files consist of: 1) definition of the
chemical system;
2) plot information; and
3) concentrations
(ranges) for the chemical
components*.
The plot information for PREDOM is as follows:
[EH,] [ONE AREA, NAME,]
YCOMP, XCOMP, MCOMP,
where data within [] are optional.
YCOMP, XCOMP = names for components with concentration in the Y-axis and X-axis,
respectively.
MCOMP = name for the central component (the component for which the
predominance areas will be calculated).
If before YCOMP, the text ONE AREA, is found,
the name of a species is read next, and the diagram will only show the
predominance area for that species.
If before YCOMP, the text EH, is found,
the redox potential (instead of pe) is displayed.
A list of possible diagram types may be obtained from PREDOM by entering a
? in the plot-definition input line,
and running the program: this will make PREDOM complain that ?
is not a correct diagram type, and the program will print a list of choices for the
plot definition.
Several input file examples may be found in
subdirectory .\EXAMPLES.
* Note: the concentration type TV
(Total concentration Varied) can not be
given for PREDOM. Use instead LTV (Log(Total
concentration)
Varied).
