*DENSITY

Keyword type: model definition, material

With this option the mass density of a material can be defined. The mass density is required for a frequency analysis (*FREQUENCY), for a dynamic analysis (*DYNAMIC or *HEAT TRANSFER) and for a static analysis with gravity loads (GRAV) or centrifugal loads (CENTRIF). The density can be temperature dependent.

First line:

• *DENSITY

Following line:

• Mass density.
• Temperature.

Repeat this line if needed to define complete temperature dependence.

Example:

*DENSITY
7.8E-9

defines a density with value $7.8 \times 10^{-9}$ for all temperatures.
