Control Cards

HyperMesh > HyperMesh Entities & Solver Interfaces:

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 editcontrol 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 nevercreated or was deleted.

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

Inactive Red A card that has been defined may be

disabled. The attributes for that cardremain; 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 enterdata in the field.
