The specific details for a criterion are displayed in the table in the top-right of the dialog:

Criterion details table

To edit the parameters for a specific criterion, click on the criterion’s name in the tree and the criterion’s parameters will be displayed in the table on the right. Edit the parameters as required and then select the next criterion to be edited from the tree, or click the dialog’s Close button. Please note that the criteria are updated as you change their data and that there is no “Cancel” function for this dialog. If in doubt, use the File | Save Criteria command to save a copy of your current criteria selection and data before making any changes in the Criteria dialog.

The parameters that may be adjusted have a white background; those which cannot be edited, have a grey background.

The values that are required for passing a criterion are in bold.

There is some subtly different behaviour for the check boxes in the dialog depending on their context. In most cases there will be group of related options used to define a criterion parameter. For example the limits for an upper integration range or the individual criteria to be evaluated for a more complex criterion:

In both of these cases the selection is cumulative and none of the selections are mutually exclusive. However, at least one must be selected.

In other cases, where the items are mutually exclusive, the check boxes act as radio buttons and only one may be selected. This occurs, for example, with the “Value of GMt at” criterion:

Finally a check box can be used to select whether a specific effect should be included, for example, GZ curve reduction in the wind heeling criteria:

There are some subtle differences between the wordings for different criteria. For example one criterion may state “Shall be greater than…”, whereas another may state “Shall not be less than…”. Hydromax allows you to make this distinction by selecting the required comparison from a combo-box in the criterion row of the details table:

Criteria may be defined as intact or damage stability criteria (or both). Intact criteria are only evaluated for the intact case and damage criteria are evaluated when a damage case has been selected (irrespective of whether there are actually any damaged compartments or tanks in the damage case). Criteria that are defined for both are always evaluated.

These options may either be set using the right-click menu or by ticking the appropriate boxes in the bottom of the dialog:

Intact and Damage tick-boxes.
