In the Auto Setup interface, the menu bar includes four menus illustrated in Figure 8.2.5. The functions provided in each menu are described in subsequent sections.
Figure 8.2.5 Auto Setup Menu Bar
The functions listed in Setup menu includes New, Save, Clear and Exit.
NEW - Create a new simulation setup. After this option is selected, a dialog box is displayed to allow the user to perform new simulation setup.
SAVE - Save current setup information in existing database.
CLEAR - Delete all the setup information in AUTO SETUP. Prior to performing Clear operation, the user must confirm the operation using the Confirmation dialog box.
EXIT - Exit Auto Setup dialog box and return to eta/DYNAFORM main interface.
The Tools menu provides functions such as Trimming, Display, Positioning, Drawbead and POP Line.
TRIMMING - Trim the blank. Both blank and trimline must be defined prior to trimming operation. For detailed description of trimming operation, refer to Section 5.3.10.
DISPLAY - Manage the display of tools via Tool On/Off dialog window illustrated in Figure 8.2.6.
Figure 8.2.6 Tool On/Off
POSITIONING - This function is used to adjust the initial position of tools and blank in stamping simulation. This function supports auto and manual positioning. For detailed description of positioning function, refer to Section 8.2.4.4.
DRAWBEADS - This function allows the user to setup drawbeads. Detailed descriptions of drawbead are provided in Section 10.4.
POP LINES - This function allows the user to define the POP line of punch and print such information into the index file. Therefore, the user can read in the POP line information in Post-processor. For detailed description of POP line, refer to Section 14.1.5.
This function enables the user to validate the motion of tools and review setup information. The ANIMATION function allows the user to preview motion of each tool assigned with either velocity or displacement curve. The SUMMARY function allows the user to review the setup information.
ANIMATION - Animate the movement of tools. After selecting this function, the Animate dialog box as shown in Figure 8.2.7 is displayed. Detailed description of the animation control is provided in Section 10.11.

SUMMARY - This function lists information of the current setup, which includes stamping direction, tool, blank, numbers of process, process name and contact type, etc. A typical Summary output is illustrated in Figure 8.2.8.
Figure 8.2.8 Summary output
The functions provided in this menu include LS-DYNA INPUT FILE, FULL RUN DYNA and JOB SUBMITTER.
LS-DYNA INPUT FILE - This function enables the user to output LS-DYNA input deck to the directory for the current database.
FULL RUN DYNA - This function enables the user to directly run a job on LS-DYNA Solver. Click this menu to display the Save dialog box. After saving the file, the program will automatically start LS-DYNA for calculation. The user can only specify solver and memory for all the stages, rather than setup solver and allocate memory for each stage.
JOB SUBMITTER - This function allows the user to submit and run the stamping simulation model. It is recommended to use this method to submit jobs for calculation..
If Job submitter is used, the location of the solver will be specified by it. The Jobs Submitter dialog box is illustrated in Figure 8.2.9. If there is no job in the job list, LS-DYNA will be run directly.

For multiple stages, the user can double click the label Type in job submitter to set the solver precision and memory size for each stage. The Multiple Stages dialog box is illustrated in Figure 8.2.10.
Figure 8.2.10 Multiple Stages dialog box
OPTIONS… - Job options. This function allows the user to specify solver precision and path, allocate memory and specify job ID. The Job options dialog box is illustrated in Figure 8.2.11.
Figure 8.2.11 Submit Job dialog box
Solver: Enable the user
to select either Single or Double Precision solver for running the current job.
The user may click on button to set the paths
for Single and Double Precision solvers. This option is only available for Full
Run Dyna submitting method.
Specify memory (MB): Specify memory allocation for current job. The default value is 128MB. The user may specify different memory allocation according to the size of model.
Specify job ID: Specify job ID. In Single stage analysis, the user is allowed to specify the default job ID or not to specify any job ID, namely not to use the prefix for the result file. However, in multi-stage analysis, the program will automatically specify job ID which cannot be specified by the user.
OK: Accept the modification and exit Job options dialog box.
Cancel: Exit Job options dialog box.
