A material definition can include two different density values:
- The density value,
, described in this topic, which is a material option in the Simulation
domain.
- A density value that you can specify in the PLM attributes of the material.
By default, simulations refer to the density value in the Simulation domain for calculations
of material behavior in an analysis. However, you can use the density value in the PLM
attributes if you prefer.
You can define material density that varies with temperature or based on the values of field
variables, but only when you use the density value specified in the Simulation domain.

Density |
Mass per unit volume of a material,

Use core material data |
Uses the density value in the material's PLM attributes to populate the
Density for this material option in the Simulation domain
with the value of the Density in the material's PLM
attributes. |
Use temperature-dependent data |
Specifies material parameters that depend on temperature. A
Temperature field appears in the data table. For more
information, see Specifying Material Data as a Function of Temperature and Independent Field Variables. |
Number of field variables |
Specifies material parameters that depend on field variables.
Field columns appear in the data table for each field
variable you add. For more information, see Specifying Material Data as a Function of Temperature and Independent Field Variables. |
