Elements that store alpha-numeric information in your model. Data elements include
Arrays, curves, splines, matrixes, and strings.
Note that data elements by themselves do nothing. They simply hold supporting data for other Adams elements or for your user function
Expressions or
User-written subroutines. For example, you reference matrices in the definition of a linear state equation. In addition, a linear state equation uses arrays of variables to define input, output, and state characteristics. You can also use curves to create contact constraints.
