Defining XY data for LS-DYNA solutions

You can use the DEFINE_CURVE modeling objects to define XY data in LS-DYNA solutions. For example, you can create a DEFINE_CURVE modeling object to define how to vary a load, such as an Acceleration load over time. The options in the DEFINE_CURVE dialog box correspond to the variables for the *DEFINE_CURVE keyword.
