*DENSITY

Specify material mass density.

This option is used to define a material's mass density. In an Abaqus/Standard analysis spatially varying mass density can be defined for solid continuum elements using a distribution (Distribution Definition).

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variables included in the definition of the density, in addition to temperature. If this parameter is omitted, it is assumed that the density is constant or depends only on temperature. See Material Data Definition for more information.

This parameter is not relevant in an Abaqus/Standard analysis if spatially varying density is defined using a distribution. See Distribution Definition.

PORE FLUID

This parameter applies only to Abaqus/Standard analyses.

Include this parameter if the density of the pore fluid in a porous medium is being defined.

SLURRY

This parameter applies only to Abaqus/Standard analyses.

Include this parameter to define the mass density of the carrier fluid and the solid particles, respectively, as well as the particle diameter.

Data lines to define mass density

First line
  1. Mass density. (Units of ML−3.)

  2. Temperature.

  3. First field variable.

  4. Second field variable.

  5. Etc., up to six field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six)
  1. Seventh field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define the density as a function of temperature and other predefined field variables.

Data lines to define mass density and the proppant particle diameter with the SLURRY parameter

First (and only) line
  1. Mass density of the carrier fluid. (Units of ML−3.)

  2. Mass density of the proppant particles. (Units of ML−3.)

  3. Diameter of the proppant particles.

First (and only) line
  1. Distribution name. The data defined in the distribution must be in units of ML−3.
