ANALYSIS SETUP
This function
enables the user to define forming parameters for the LS-DYNA ANALYSIS. The
dialog window is shown in Figure

DRAW TYPE
The user can select a draw type, as shown in Figure

GRAVITY ONLY
No punch and die is used as the blank is deformed by gravity.
SINGLE ACTION
The punch (male piece) is above the blank.
DOUBLE ACTION
The punch (male piece) is below the blank.
SPRING BACK
Residual stresses deform the imported blank (DYNAIN file).
USER DEFINE
The DRAW TYPE is user defined.
Note: The defined DRAW TYPE works in conjunction with the BLANKOPERATION/AUTO POSITION and TOOL/AUTOPOSITION

CONTACT INTERFACE
There
are several types of contact interface available for an LS-DYNA stamping
simulation as listed in Figure
Note: Please refer to the LS-DYNA User's Manual, keyword *CONTACT, for more detailed information about each of the contact interfaces.
STROKE DIRECTION
The user can define stroke direction in X, Y, or Z.
CONTACT GAP
The contact gap is the minimum distance between the tooling and blank after auto-positioning. The default contact gap is set to 1.0. The contact gap will be overwritten if blank thickness is defined.
SOLVER
This function determines the location of the LS-DYNA
solver using the SELECT SOLVER window as shown in Figure
