Control Cards

Control card entities are used to create solver control cards such as results file I/O options, CPU and memorylimits, and others. A solver interface template must be loaded which defines control cards in order to create andedit control cards. Control cards are shown under the Card folder within the Model Browser.

The following panels can be used to create and edit control cards:

*DATABASE_OPTION cards in Keyword are listed from the Setup drop down menu, after selecting ControlCards. An active field is output as the appropriate individual card in the data deck.

A control card can be in one of three states:

State Color Explanation

Undefined Gray The control card was either never createdor was deleted.

Defined (See Note) Green Any control card viewed in the cardpreviewer is activated.

Inactive Red A card that has been defined may bedisabled. The attributes for that cardremain; however, the control card is notoutput.

Note: Those control cards that are defined (green in the control card editor) are output.

Default values for attributes are common throughout the card previewer. A default value field has one of thefollowing states:

State Description

Default = ON In this state, the field label color is yellow and no dataentry is allowed.

Default = OVERRIDDEN To override a default value field, pick the yellow fieldlabel. When you override a default value field, the labeltext color changes to cyan and you can enter data inthe field.
