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 typical 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 generate related variable sets.
4. Prepare output. This can be via graph plots, tabular listings or file output.
The following POST26 topics are available:
8.1.The Time-History Variable Viewer
8.2. Entering the Time-History Postprocessor
8.3. Defining Variables
8.4. Processing Your Variables to Develop Calculated Data
8.5. Importing Data
8.6. Exporting Data
8.7. Reviewing the Variables
8.8. Additional Time-History Postprocessing
8.1. The Time-History Variable Viewer
You can interactively define variables for time-history postprocessing using the variable viewer. A brief description
of the variable viewer follows.
1. TOOLBAR
Use the toolbar to control your time-history operations. You can collapse the two expansion bars (2
and 4 below) and retain a compact toolbar that includes these items.
