Adding a Function to the Material

Material functions are either automatically added to the Model Builder sequence (usually with materials from the material library) or functions can be added based on individual requirements.

1	Add a material to the Component node (see The Material Browser Window and The Add Material Window ).

2	Add an Analytic (), Interpolation (), or Piecewise () function.

To add an Analytic (), Interpolation (), or Piecewise () function: • On the Materials toolbar, click Analytic, Interpolation, or Piecewise. • Right-click a property group node (for example, Basic) and select a function from the Functions list.

To add an Analytic (), Interpolation (), or Piecewise () function: • Right-click a property group node, for example, Basic and select a function from the Functions list. • On the Materials contextual toolbar, click Analytic, Interpolation, or Piecewise.

-	Select Analytic to add an analytic function of one or more input arguments.

-	Select Interpolation to add an interpolation function that can interpolate from structured data (defined on a grid) or unstructured data (defined on a generic point cloud).

-	Select Piecewise to add a piecewise function that is useful if a material property has different definitions on different intervals. The intervals must not overlap, and there cannot be any holes between intervals.

• Defining an Analytic Function • Analytic, Interpolation, and Piecewise

Once a function is created, you can use it for any property in the same property group.
