LSWRITE! Write load data to load step file
Etc.5.3.7. Save a Backup Copy of the Database
Save a copy of the database to a named file. You can then retrieve your model by reentering the program
and issuing RESUME.
Command(s):SAVE
GUI: Utility Menu> File> Save as
5.3.8. Start the Transient Solution
Use one of these methods to start the transient solution:
Command(s):LSSOLVE
GUI: Main Menu> Solution> Solve> From LS Files
For additional ways to create and solve multiple load steps (the arra y parameter method and the multiple
SOLVE method), see Solving Multiple Load Steps in the Basic Analysis Guide.
5.3.9. Exit the Solution Processor
Use one of these methods to exit the solution processor:
Command(s):FINISH
GUI:Close the Solution menu.
5.3.10. Review the Results
You review results for a full transient analysis in the same way that you review results for most structural
analyses. See Review the Results (p. 19) in Structural Static Analysis (p. 9).
5.3.10.1. Postprocessors
You can review these results using either POST26, which is the time-history postprocessor, or POST1,
which is the general postprocessor.
- POST26 is used to review results at specific points in the model as functions of time.
- POST1 is used to review results over the entire model at specific time points.
Some typical postprocessing operations for a transient dynamic analysis are explained below. For a
complete description of all postprocessing functions, see Postprocessors Available in the Basic Analysis
Guide.
5.3.10.2. Points to Remember
The points to remember for a full transient analysis are the same as those for most structural analyses.
See Points to Remember (p. 19) in Structural Static Analysis (p. 9).
5.3.10.3. Using POST26.
POST26 works with tables of result item versus time, known as variables. Each variable is assigned a
reference number, with variable number 1 reserved for time.
- Define the variables.
