LS-DYNA (GRAVITY LOADING)

If the draw type is set to GRAVITY (TOOLS/ANALYSIS SETUP/DRAW TYPE), the Analysis dialog box illustrated in Figure 14.3.1 is displayed when clicking LS-DYNA. The user can refer to Section 10.1 Analysis Setup for detailed description about the setup of draw type. There are three methods provided here to solve the gravity loading: Explicit (Dynamic Relaxation), Implicit (Dynamic) and Implicit (Static). The Implicit (Static) method is recommended. When the Implicit (Static) method is selected, the solver will be defaulted to be double precision. Once the solve method is selected, the user can click Dynamic Relaxation (or Implicit Parameters) button to set the relevant parameters.
