Chapter 8: The Time-History Postprocessor (POST26)

Use the time-history postprocessor to review analysis results at specific locations in the model as a
function of time, frequency, or some other change in the analysis parameters that can be related to
time. In this mode, you can process results data in many ways. You can construct graphics displays,
chart representations or tabular listings, or you can perform math operations on your data sets. A typ-
ical time-history task would be to graph result items versus time in a transient analysis, or to graph
force versus deflection in a nonlinear structural analysis.

Following is the general process for using the time-history postprocessor:

1. Start the time-history processor, either interactively or via the command line.


2. Define time-history variables. This involves not only identifying the variables, but also storing the
   variables.


3. Process the variables to develop calculated data or to extract or generat e related variable sets.


4. Prepare output.This can be via graph plots, tabular listings or file output.
