Chapter 8:The Time-History Postprocessor (POST26)
8.7.2.1. Interactive
The "List Data" button of the variable viewer can be used to list up to six variables in the variable viewer.
When listing complex data such as from a harmonic analysis, use the 'results to view' drop-down list on the
right top corner of the variable viewer to indicate whether to printout "amplitude and phase angle" or "real
and imaginary parts" in the listing. Select amplitude or phase to list “Amplitude and Phase Angle” results.
Select real or imaginary to list “Real and Imaginary” results.
You can restrict data being listed to a range of time or frequency. This and other listing controls are available
through the "Lists" tab under Data Properties dialog. In addition to setting the range of time or frequency,
this dialog also allows you to:
• Control the number of lines before repeating headers on the listings.
• Additionally print the extreme values of the selected. variables.
• Specify printing every 'n'th data point.
8.7.2.2. Batch
You can use the PRVAR command (Main Menu> TimeHist Postpro> List Variables) to list up to six variables
in tabular form. This is useful if you want to find the value of a result item at a specific time or frequency.
You can control the times (or frequencies) for which variables are to be printed. To do so, use one of the
following:
Command(s): NPRINT, PRTIME
GUI: Main Menu> TimeHist Postpro> Settings> List
You can adjust the format of your listing somewhat with the LINES command (Main Menu> TimeHist
Postpro> Settings> List). A sample PRVAR output is shown below.

When a complex variable consists of real and imaginary parts, the PRVAR command lists both the real and
imaginary parts by default. You can work with real and imaginary, or amplitude and phase angle using the
PRCPLX command.
Another useful listing command is EXTREM (Main Menu> TimeHist Postpro> List Extremes), which prints
the maximum and minimum Y-variable values within the active X and Y ranges. You can also assign these
extreme values to parameters using the *GET command (Utility Menu> Parameters> Get Scalar Data). A
sample EXTREM output is shown below.
