Control Cards

Control card entities are used to create solver control cards such as results file I/O options, CPU and memory limits, and others. A solver interface template must be loaded which defines control cards in order to create and edit 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 Control Cards. 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 created or was deleted.
Defined (See Note)	Green	Any control card viewed in the card previewer is activated.
Inactive	Red	A card that has been defined may be disabled. The attributes for that card remain; however, the control card is not output.

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 the following states:

State	Description
Default = ON	In this state, the field label color is yellow and no data entry is allowed.
Default = OVERRIDDEN	To override a default value field, pick the yellow field label. When you override a default value field, the label text color changes to cyan and you can enter data in the field.
