ANALYSIS TYPE
There are three types of analysis output:
1. LS-DYNA INPUT FILE
This function outputs the setup results as an LS-DYNA input deck.
2. FULL RUN DYNA
This function outputs a LS-DYNA input deck and launches the LS-DYNA to run the current job immediately.
NOTE: The user should set the path of the LS-DYNA solver in Tools/Analysis Setup menu.
3. JOB SUBMITTER
This function outputs a LS-DYNA input deck and submits it to Job Submitter. Then, the user can manage the job in Job Submitter. The GUI is illustrated in Figure 13.1.2.

The user can select the type of analysis output by clicking on the toggle menu.
CONTROL PARAMETERS
This function defines the control parameter values for running a stamping simulation using LS-DYNA. The user can edit the parameters by clicking on the CONTROL PARAMETERS icon from the ANALYSIS dialog box. The DYNA3D CONTROL PARAMETER dialog box is shown in Figure 13.1.3.

TERMINATION TIME
Determine by the time duration of motion curve.
TIMESTEP (DT2MS)
Time step size for mass scaling. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_TIMESTEP for more information.
PARALLEL (NCPU)
This setting allows the user to define the number of processors to be used by the solver. This function requires PC hardware with multiple processors, a shared memory (parallel process) version of the LS-DYNA solver, and valid license. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_PARELLEL for more information.
STATES IN D3PLOT (DPLTC)
This setting allows the user to define the number of evenly spaced frames of data, displayed and animated in eta/POST. Please refer to the LS-DYNA Keyword User¡¯s Manual, *DATABASE_BINARY_D3PLOT for more information.
ADVANCED OPTIONS
HOURGLASS (IHQ)
Optional hourglass force vector modifier. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_HOURGLASS for more information.
CONTACT (SLSFAC)
Scale factor for sliding interface penalties. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_CONTACT for more information.
CONTACT (ISLCHK)
Initial penetration check in the contact surfaces. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_CONTACT for more information.
CONTACT (SHLTHK)
Shell thickness considered in SURFACE-TO-SURFACE and NODE-TO-SURFACE contact options. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_CONTACT for more information.
CONTACT (PENOPT)
Penalty stiffness value option. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_CONTACT for more information.
TERMINATION (ENDMAS)
Percent change in the total mass for termination of calculation. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_TERMINATION for more information.
INTEGRATION (MAXINT)
Number of shell integration points. Please refer to the LS-DYNA Keyword User¡¯s Manual, *DATABASE_EXTENT_BINARY for more information.
OUTPUT TIMES (ENDTIM/DT)
Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_TERMINATION for more information.
ACCURACY STRESS (OSU)
Global flag for objective stress updates. Please refer to the LS-DYNA Keyword User¡¯s Manual, * CONTROL_ACCURACY for more information.
ACURACY NODE (INN)
Invariant node numbering for shell elements. Please refer to the LS-DYNA Keyword User¡¯s Manual, *CONTROL_ACCURACY for more information.
OK - Accepts the control parameters.
DEFAULT - Resets all values to their default settings.
RESET - Resets the last defined setting to its previously defined value.
ADVANCED - Extends the table to make the advanced control parameters show up.
CANCEL - Aborts the table and resets all values to their previous settings.
NOTE: Refer to the LS-DYNA User's Manual for detailed information about each control parameter.
