7.3. Using the PGR File in POST1
The PGR file is a specialized graphics object that stores the graphical information you develop during the
Solution phase of your analysis. By storing this “precooked” information, you can access it in POST1 markedly
(up to 10X) faster. Although the greatest benefit will be achieved when you designate the items to be saved
before you initiate the solution, you can generate a PGR file, with all of the same information, from your
existing results file(s). You can also append new solution data to your existing PGR file in POST1. For more
information on creating your PGR file in Solution, see Using the PGR File to Store Data for Postprocessing (p. 109)
in Chapter 3 of this manual.
The three sections that follow cover the operations that are available in POST1. The links below correspond
to the appropriate GUI dialog boxes.
Specifying a new PGR file in POST1, see Specifying a New PGR File in POST1 (p. 168), below.
Appending an existing PGR file in POST1, see Appending to an Existing PGR File in POST1 (p. 170), below.

7.3.1. Specifying a New PGR File in POST1
Although you obtain the greatest speed advantage by specifying the PGR file BEFORE solving your analysis,
you can always generate a PGR file AFTER you have completed your solution. This process reads the data
from your results file (*.RST, *.RFL, *.RTH, *.RMG, etc.) and generates the display data, basically
from scratch. Generating a new PGR file allows you to take advantage of the flexibility of the Results Viewer
and the speed of the PGR file data access to view your solution data and generate plots, data tables and
animations. The Results Viewer provides an ideal platform from which to review and process various portions
of your solution data, or to rapidly access and compare data from multiple solutions.
Once you have completed your solution, or loaded your results file, you can create a PGR file in POST1. You
create a PGR file in POST1 by selecting Main Menu> General Postprocessor> Write PGR File. The following
dialog box appears:
