The analysis of a stage is set up using the Analysis wizard from the Analysis > New analysis task command. Select the option to create a new analysis and select the analysis stage. The remainder of the data in the wizard is entered in the usual way.
The analysis stage facility allows the elements, element properties, restraints and constraint conditions to be specified for particular analysis cases. It is provided to allow the results from models differing in these ways to be combined (e.g. for the analysis of construction stages).
Results are produced for analysis stages in the same way as for whole model analysis. Values of zero are stored for nodes and elements that are inactive for the stage.
Graphic Views can be set to display a specific stage. The stage is specified on the Lists toolbar for the Graphic view by first setting the Display option to Stages and then selecting the required stage in the Display list. The Stages display option is not offered when no stages are present in the model. The stage can also be set in the in the Graphic settings dialog box.
