The changes you make are automatically stored in the database and reflected in the Workspace tree and the Damage Case view.

Grouping compartments with respect to single free surfaces

Once you’ve defined a damage case following the steps described above, it will comprise two compartment groups at most, "Primary 1" and, if you added cross-flooded compartments, "Cross 1", each group representing a single free surface. To group the compartments within these groups in order to specify several free surfaces, follow these steps:

1. In the Workspace, select the damage case. The selection will be reflected in the Graphics window.
2. In the Workspace, press the button Single Free S’face Group. The marker in the Graphics window will have a shape of a bar to indicate the position of the section.
3. In the Graphics window, position the section by moving the marker bar, and select the compartments to be grouped. Clicking on a selected compartment deselects it.
4. In the context menu for the graphics window, click Group. The selected compartments will be placed in one group.

A particular compartment can’t be found in several groups. Placed in a new group, it will be automatically removed from the group it previously belonged to.

To create a lesser extent damage case

The lesser extent damage cases are derived from the existing damage cases. The procedure is as follows:

1. Create a copy of the original maximum extent damage case
2. Edit the copy of the damage case with respect to which of the originally damaged compartments should be excluded.

The number of lesser extent damage case you can derive from one particular damage case is unlimited. These are the steps you should follow:

1. In the Workspace, select the original maximum extent damage case. The selection will be reflected in the Graphics window.
2. In the context menu for the selected damage case, click Copy As Less Extent. A new damage case will be added to the All Damage Cases folder. Its name will consist of the name of the original damage case and the appendix ‘Less 1(2,3,4...)’.
3. In the Workspace, press the button Less Extent. The marker in the Graphics window will have a shape of a bar to indicate the position of the section.
4. In the Graphics window, position the section by moving the marker bar, and select the compartments to be excluded. Clicking on a selected compartment deselects it.

The changes you make are automatically stored in the database and reflected in the Workspace tree and the Damage Case view.

To change the compartment name format

1. In the context menu for the workspace, select Properties.
2. In the appeared ‘Tree properties’ dialog box, select the option of how the compartment name will appear in the tree and press OK.

3. In the appeared Flooding Stage dialog, choose the stage to be applied and press OK. The Flooding Stage dialog will not appear, if there is only one flooding stage, it will be applied directly.

The current condition will be changed with respect to the applied damage case. It can then be analysed in all the views related to the currently active condition.

To evaluate a damage case with respect to a criteria set.

1. In the View menu, click Criteria Evaluation to open the Criteria Evaluation View.
2. In the Workspace, select a damage case. The selection will be reflected in the Graphics window.
3. In the Criteria Evaluation view, check the Apply damage case check box. The damage case will be evaluated according to the specified criteria set. The results can then be studied in the Criteria Evaluation view for the most critical stage. The most critical stage is shown next to the damage case name. (To view the results for all the stages use the Damage Results view.)
4. In the appeared Flooding Stage dialog, choose the stage to be applied and press OK. The Flooding Stage dialog will not appear in case there is only one flooding stage, the final stage will be applied directly.

Applying a damage case in the Criteria Evaluation view does not affect the current condition. It only affects the information in the Criteria view.
