In the Control definition page, the user is allowed to set up basic parameters to control gravity simulation such as General LS-DYNA parameters and Analysis method. There are three methods provided here to solve the gravity load: Explicit (Dynamic relaxation), Implicit (Dynamic) and Implicit (Static). It is recommended to use the Implicit (Static) method. Control definition page is illustrated in Figure 8.3.93.

TERMINATION TIME (ENDTIM): Termination time.

ADVANCED: Advanced setup of basic parameters. The dialog box is illustrated in Figure 8.3.94.

ANALYSIS METHOD:

·           Explicit (Dynamic Relaxation)

·           Implicit (Dynamic)

·           Implicit (Static)

Once the Explicit (Dynamic relaxation) method is selected, the user can click the Advanced button to set the advanced parameters for dynamic relaxation. The interface is illustrated in Figure 8.3.95.

Once the Implicit (Dynamic) method is selected, the user can click the Advanced button to set the advanced parameters for it, as illustrated in Figure 8.3.96.
