SPRINGBACK (SEAMLESS)
This function toggles on/off the LS-DYNA seamless explicit/implicit switch. It will activate implicit springback analysis after the stamping simulation. If SEAMLESS is toggled on, the user can set the springback constraint and define the IMPLICIT parameters as shown in Figure 13.1.4.

ADAPTIVE MESH (toggle)
If this function is toggled on, ADAPTIVE scheme is activated during the stamping simulation. The user can edit the adaptive parameters by clicking on the ADAPTIVE PARAMETERS button. The default ADAPTIVE CONTROL PARAMETERS dialog window is shown in Figure 13.1.5. The ADVANCE button enables the user to expand the dialog window for more adaptive parameters.
