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:

Solver Card Support for Control Cards

Control cards define model information, which needs to be specified only once in the input file. The following Abaqus keywords are supported as control cards:

Supported Card	Solver Description	Supported Parameters	Notes
*CONSTRAINT CONTROLS	Reset overconstraint checking controls	NO CHECKS NO CHANGES DELETE SLAVE
*DEPVAR	Specify solution-dependent state variables	svcount
*HEADING	Print a heading on the output	Title MultipleLines
*PREPRINT	Select printout for the analysis input file processor.	CONTACT ECHO HISTORY MASS PROPERTY MODEL
*RESTART	Save and reuse data and analysis results	READ WRITE STEP INC END STEP FREQUENCY OVERLAY

The last step before creating the Actran input deck is completing control cards, which define the properties of the model that are not directly related to the mesh. You can define the title, analysis specifications, dimensions of the problem, interfaces between incompatible meshes, a color map and frequency response function solution, external structural vibration, and acoustic sources.

Control cards can be accessed from the Control Cards panel:

*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.
