Code Manual for CONTAIN 2.0 - Federation of American Scientists

16.4.1.3 Bin ary Plot File (PLTFIL). POSTCON processes the CONTAIN binary plot fde. This file
is described in detail in Section 16.3.1.1. The name of this file is PLTFIL by default; however, this
name can be changed in the FDB of the POSTCON input file (see Sections 16.4.3 and 16.4.4). As
can be seen in Figure 16-1, PLTFIL is an input to the POSTCON process. Because the plot file is
used during POSTCON initialization, it must always be present, even if no processing of the binary
plot file is to be performed during a particular POSTCON run.
16.4.1.4 Table Outmt File (POUT). Postprocessed CONTAIN dat~ organized in tabular form, are
written to a file named POUT by default. As can be seen from Figure 16-1, these tables are
generated before the mixing process, so the tables cannot reflect the results of mixing.
The POSTCON tables are comprised of a collection of data curves presented in columns. All curves
in any one table correspond to the same plot flag and TBD, with the possible exception of snapshot
curves. For example, one column in the table for plot flag 101 maybe the temperature in cell 1, and
another may be the temperature in cell 2. Further discussion of table curves is given in Section 16.6.
The tables generated by POSTCON normally consist of a maximum of eight columns per section.
If there are more than nine curves in a TBD, then the table will be printed in two or more
appropriately labeled sections. An exception to this rule is made when a table can be completed by
including a ninth column in the last section. This prevents a single column from being placed in a
section by itself (unless of course there is only one column in the table). Each table (or table section)
is printed with the correct unit labels and a brief descriptive title. The tables are formatted using
FORTRAN carriage control in pages of length 66 with titles appearing on each page and new tables
beginning on a fresh page. The minimum, maximum, and average of the extracted values are printed
at the bottom of each table column. NOTE: Since POSTCON can extract data at user-defined time
intervals, the minimum, maximum, and average values reported may not apply to the entire
calculation.
16.4.1.5 Vector File (PVEC]. Postprocessed CONTAIN data, organized in vector form, are written
to a fde named PVEC by default. A vector is an x-y data pair, normally with time as the independent
variable. The primary function of the vector file is to provide an interface between CONTAIN
results and a graphics package.
The PVEC file also serves as an input file for the mixing process. Vectors are read in from the
PVEC file and the manipulated results are output, as vectors, to the PMIX file.
16.4.1.6 ~). The mix file is created by the POSTCON mixing process. When
algebraic manipulations are performed on vectors from the PVEC fde, the results are written to a fde
named PMIX by default. The format of this file is identical to that of the PVEC file.
If a curve, or set of vectors, cannot be found in the PVEC file, the PMIX file is also searched. This
allows the user to create a curve with one mix expression and refer to that curve in a later expression.
Thus, the PMIX file is both an input to and an output from the mixing process of POSTCON.
