Set Load Cases to Run and Run Analysis

Form: Set Load Cases to Run

The Analyze menu > Set Load Cases to Run and Analyze menu > Run Analysis commands both open the Set Load Cases to Run form. Use that form to check the analysis status of the cases, delete results for cases that have already been run, set which cases are to be run, and run the analysis or just save the settings.

The table on the form lists all defined load cases and shows the following:

Case Name: The name defined for a load case.
Type: The type of load case.
Status: Shows the status of the case following its most recent analysis. Values are:
Not Run: The case has never been run or its results have been deleted.
Could Not Start: An attempt was made to run the case, but a prerequisite case was not finished.
Not Finished: The analysis was unable to reach its requested final state.
Finished: The analysis completed successfully.
Action: A value set by the user indicating what should happen the next time an analysis is run:
Run: Indicates that SAP2000 should run the load case.
Do Not Run: Indicates that SAP2000 should not run the load case.
Run/Do Not Run Case button. Highlight a load case and click the Run/Do Not Run Case button to toggle analysis on and off. When Run displays in the Action List, the analysis will begin and all cases set to run and their prerequisite cases will be run.
Delete Results for Case button. Highlight a Case Name and click the Delete Results for Case button to delete results for the selected case. The status of those cases will be set to Not Run.

Note: To delete a load case, click the Define menu > Load Cases command to access the Define Load Cases form. Highlight the case to be deleted and click the Delete Load Case button.

Run/Do Not Run All Cases button. Use the Run/Do Not Run All Cases button to toggle all load cases on or off simultaneously.
Delete All Results button. Use the Delete All Results button to delete all cases simultaneously. If results for one case are deleted, the results for all cases that depend upon that case are also deleted.

Important: When you delete results, you will be asked for confirmation. After results have been deleted, they cannot be recovered except by rerunning the analysis. Clicking the Cancel button will not undelete them.

Show Load Case Tree button. Click this button to display the Load Case Tree form. As the name suggests, the form displays a tree of the load cases defined for the model. Use the Expand All or Collapse All buttons on the form to show all cases or limit the display of cases, respectively. With the load cases displayed, right click on a load case name to display the form needed to edit that load case. With the form displayed, click the F1 key on the keyboard to display context-sensitive Help for that form.

Note: The Show Load Case Tree button also appears on the Define Load Cases form.

Model-Alive™ check box. When this check box is checked, the model analysis updates automatically each time changes are made; that is the model updates without executing the Run Analysis command. The Model-Alive™ feature can be especially useful on smaller models because it allows the user to instantly see the effects of any model revision. The Model-Alive™ feature will not be as beneficial on larger models with longer run times.
Run Now button. Click the Run Now button and the cases set to Run will be run.
OK and Cancel button. Click the OK button and the action settings will be saved but the analysis will not run. Click the Cancel button and the action settings will be left unchanged.
Analysis Monitor Options. Use these options to specify when the Analysis window displays. Scrolling through the information provides the opportunity to check for any warnings or errors that might invalidate your analysis. Also note that this information is saved, in text form, in the .LOG file. Access the .LOG file using the File menu > Show Input/Output Text Files command, or any text editor or word processing program.
- Always Show option. When this option is selected, the Analysis window will display during the entire analysis processing period.
- Never Show option. When this option is selected, the analysis will run, but the Analysis window will not display, and thus, the results will not be shown. To review the results, click the Analyze menu > Show Last Run Details command to display the most recent analysis results in the Analysis window.
- Show After ___ seconds option. When this option is selected, specify the number of seconds to elapse before the Analysis window displays.

Note: As the analysis is running, a Show Details button will be added to the Status bar. Clicking this button will display the results in the analysis window if they are not already displayed. Also, after an analysis has been run, the Analyze menu > Show Last Run Details command can be used to display the most recent analysis results in the analysis window. The Less/More buttons on the Analysis window can be used to decrease the size of the form, or restore it to full size, respectively.
