Forging uses control cards to describe the steps of a forging process. The control cards can be accessed from the Control Cards panel, which is available on the main panel.

control_cards_forging

A control card may be in one of three states:

State

Color

Explanation

Undefined

Gray

The control card was never created or was deleted.

Defined

Green

The control card has been activated. Cards become activated when they are opened in the card previewer. All control cards that are defined are output.

Inactive

Red

The card is defined, but is disabled. The card retains its attributes but is not output.

Default values for attributes are common throughout the card previewer. A default value field has two 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 information in the field.

 

Each control card contains keywords that relate to the particular category. Most of the keywords have been completed with default values. You need to provide values for only a few keywords, which are listed with the associated control cards below.  Refer to the DEFORM User’s Manual for specific information about keywords.

The control cards for forging include:

•Process Definition
TITLE: A text description of the simulation.
SIMNAM: A name to identify a simulation that is one of multiple operations.
TNOW: The current simulation process time.
•Stopping Stepping
SMAX: Terminates a simulation when the stroke of the primary object reaches a maximum value.
VMIN: Terminates a simulation when the velocity of the primary object reaches a minimum value.
LMAX: Terminates a simulation when the load of the primary object reaches a maximum value in the X or Y direction.
DSMAX: Limits the displacement of the primary object in one time step.
DTPMAX: Specifies the maximum temperature increment per time step in heat transfer calculations.
DVMAX: Limits the amount of volume change that can occur in an individual element or an object during one time step.
•Iteration Controls
•Process Conditions
•Advanced Controls
USRDEF: Creates storage space for user data, such as for user-defined subroutines or comments.
