iteration and convergence parameters to be read into the database, where you can incorporate
them into your postprocessing.

Other Capabilities
Many other postprocessing functions are available in POST26. See The Time-History Postprocessor
(POST26) in the Basic Analysis Guide for details.
8.6.7. Terminating a Running Job; Restarting
You can stop a nonlinear analysis by creating an "abort" file (Jobname.ABT). See Solution in the Basic
Analysis Guide for details. The program also stops upon successful completion of the solution, or if a
convergence failure occurs.
You can often restart an analysis if it successfully completed one or more iterations before it terminated.
Restart procedures are covered in Restarting an Analysis in the Basic Analysis Guide.
8.7. Performing a Nonlinear Transient Analysis
Many of the tasks that you need to perform in a nonlinear transient analysis are the same as (or similar
to) those that you perform in nonlinear static analyses (described in Performing a Nonlinear Static
Analysis (p. 242)) and linear full transient dynamic analyses (described in Structural Static Analysis (p. 9)).
However, this section describes some additional considerations for performing a nonlinear transient
analysis.
You cannot use the Solution Controls dialog box (Performing a Nonlinear Static Analysis (p. 242)) to set
solution controls for a thermal analysis. Instead, use the standard set of solution commands and the
standard corresponding menu paths.
8.7.1. Build the Model
This step is the same as for a nonlinear static analysis. If your analysis includes time-integration effects,
however, include a value for mass density (MP,DENS). If you wish, you can also define material-dependent
structural damping (MP,BETD or MP,ALPD).
8.7.2. Apply Loads and Obtain the Solution
- Specify transient analysis type and define analysis options as you would for a nonlinear static analysis:
- New Analysis or Restart (ANTYPE)
- Analysis Type: Transient (ANTYPE)
