[Sum95] and is capable <strong>of</strong> generating graphical output on a wide variety <strong>of</strong> computer plat<strong>for</strong>ms<br />

without dependence on DISSPLA. As a result, HISPLT can be used to directly generate <strong>CONTAIN</strong> ~<br />

plots once POSTCON has been used to postprocess the <strong>CONTAIN</strong> plot file. Any future<br />

development <strong>of</strong> the HISPLT package <strong>for</strong> MELCOR will also improve <strong>CONTAIN</strong> postprocessing<br />

capabilities, and <strong>CONTAIN</strong> and MELCOR users can now learn and apply a single postprocessing<br />

tool.<br />

HISPLT is similar to POSTCON in that generating plots from the data requires the construction <strong>of</strong><br />

a line command input file that generates graphical results in a batch processing mode. To eliminate<br />

the need to generate a line command input file <strong>for</strong> HISPLT by hand, a graphical user interface (GUI)<br />

program called HISPAC has been developed <strong>for</strong> the postprocessing <strong>of</strong> both CONTAJN and<br />

MELCOR results. The GUI postprocessing tool HISPAC uses the HISPLT-compatible file PLTHIS<br />

as input. The GUI serves as a transparent interface to HISPLT, and allows the user to interactively<br />

examine and plot <strong>CONTAIN</strong> results even without specific knowledge <strong>of</strong> HISPLT commands. A beta<br />

test version <strong>of</strong> HISPAC, and draft documentation, is available to <strong>CONTAIN</strong> users.<br />

<strong>CONTAIN</strong> users now have three distinct options in plotting <strong>CONTAIN</strong> results:<br />

1. Use POSTCON to generate x-y data pairs, and then generate plots with a separate plotting<br />

package.<br />

2. Use POSTCON to generate the HISPLT-compatible data file PLTHIS, then use HISPLT directly<br />

to generate plots.<br />

3. Use POSTCON to generate the HISPLT-compatible data file PLTHIS, then use the GUI HISPAC<br />

to interactively generate plots.<br />

16.2 Introduction to POSTCON<br />

The numerical results generated by <strong>CONTAIN</strong> normally take the <strong>for</strong>m <strong>of</strong> massive quantities <strong>of</strong><br />

output data. The POSTCON computer program provides an easily used and efficient method <strong>for</strong><br />

examining such results. This section describes the capabilities <strong>of</strong> POSTCON and provides<br />

instructions <strong>for</strong> its use. Its overall capabilities include extraction <strong>of</strong> all transient data from<br />

<strong>CONTAIN</strong> binary plot files, multiple fde handling, a flexible unit conversion system, snapshot and<br />

histogram options, generation <strong>of</strong> output tables, graphics output, and tools <strong>for</strong> per<strong>for</strong>ming arithmetic<br />

manipulations on the extracted data. Examples are included to clari@ the discussion <strong>of</strong> input options<br />

and output <strong>for</strong>mats.<br />

16.2.1 Objectives <strong>of</strong> POSTCON<br />

<strong>CONTAIN</strong> calculations typically produce a wealth <strong>of</strong> numerical output that could potentially<br />

overwhelm the investigator and thereby limit the usefulness <strong>of</strong> the calculations. To solve this<br />

problem, POSTCON was created to extract data from <strong>CONTAIN</strong> binary plot ffles and to present this<br />

data in a <strong>for</strong>m convenient <strong>for</strong> analysis.<br />
