33.4.10 Piecewise-Linear Profile Dialog Box

The Piecewise-Linear Profile dialog box allows you to define a physical property as a piecewise-linear function of temperature. This dialog box will open when you select piecewise-linear in the drop-down list next to a physical property in the Create/Edit Materials dialog box. See Section  8.2.2 for details about the items below.

Controls

Define   shows the property that is being defined as a function of temperature.

In Terms of   shows the independent variable ( Temperature). The property shown in Define will be defined as a piecewise-linear function of temperature.

Points   indicates the number of data pairs that will define the piecewise distribution. You can define up to 30 pairs.

Data Points   contains entries for defining the data pairs.

Point   indicates the point for which the data pair ( Temperature, Value) is being defined.

Temperature   is the independent variable.

Value   is the dependent variable (i.e., the property). In the example dialog box above, Viscosity is the variable being defined, as shown in the Define field.
