# Running analyses
# Analysis – simple static
The quickest way to run analyses is to use Analyse all on the menu or the GSA toolbar. This runs a simple static analysis or the analysis tasks that have been set up in the Analysis wizard, You can also use the Analysis > Analyse all menu command.
Individual analysis cases can be run via the Analysis tasks window in the data explorer or the Analysis task manager (available from the Analysis > Manage tasks menu command).
Giving the Analyse all command in this way automatically sets up analysis cases for each load case. (A discussion on this subject is given in Working with the program: Cases and tasks.) A Report view is opened for reporting progress during the analysis. A check is done on the data and then, provided that there are no errors a GSS static analysis is performed.
# Termination
The analysis may be aborted at any stage during the analysis by using the Stop button on the status bar or by closing the Report view.
# Post analysis
After a successful analysis the Analyse all command will be disabled and results will be available for viewing in graphic views and output views. The input data is locked against editing, since any editing of data upon which results depend would invalidate the results.
After a simple static analysis the results for load case 1 are stored in analysis case 1 etc. Since there is this unambiguous, one to one relationship between load and analysis cases in this circumstance GSA does not insist on specific reference to load cases or analysis cases. E.g. '1' may be used to refer to 'L1' and 'A1'.
# Deleting results
The results may be deleted using Analysis > Erase all results on the menu or the GSA toolbar. When the analysis cases have been set up automatically, as described in Simple static analysis above, the analysis cases are deleted with the results.
# Other analysis types & analysis wizard
Analysis cases will be set up automatically only for simple static analysis. If it is required to analyse compound load cases or analyse using a different method or solver it is necessary to set up analysis cases to describe the required analysis. This is done in the Analysis Wizard which may be opened using Analysis > New analysis task on the menu or the Data Options toolbar.
When analysis cases have been set up (in the Wizard) but not analysed yet, the 'Analyse' command is enabled and will analyse all analysis cases currently at pre-analysis status.
Using the Delete all results command when analysis cases exist that have been set up via the Analysis wizard does not automatically delete the analysis cases with the results; however the option is given to delete the analysis cases.
