Context:
See Density, for more information.
From the menu bar in the Edit Material dialog box, select .
(For information on displaying the Edit Material dialog box, see Creating or editing a material.)
Click the arrow to the right of the Distribution field, and select the option of your choice from the list that appears:
-
Select Uniform to define density that is uniformly distributed throughout the material.
-
Select an analytical field, labeled with an (A), or a discrete field, labeled with a (D), to define a spatially varying density. Only analytical fields and discrete fields that are valid for density are available in the selection list. See The Analytical Field toolset,” and The Discrete Field toolset,” for more information.
Alternatively, you can click to create a new discrete field.
Toggle on Use temperature-dependent data to define density as a function of temperature.
A column labeled Temp appears in the Data table.
Click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables on which the density depends.
Enter the following data in the Data table:
- Mass Density
Mass density. (Units of ML−3.)
- Temp
Temperature.
- Field n
Predefined field variables.
For detailed information on how to enter data, see Entering tabular data.
Click OK to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
