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).
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.
Data lines to
define mass density
First
line
Mass density. (Units of ML−3.)
Temperature.
First field variable.
Second field variable.
Etc., up to six field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six)
Seventh field variable.
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.
