Optional parameters

DEPENDENCIES

This parameter applies only to Abaqus/Standard and Abaqus/Explicit analyses.

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

PORE FLUID

This parameter applies only to Abaqus/Standard analyses.

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

The conductivity of a fluid must be isotropic; therefore, TYPE=ORTHO, TYPE=TRANSVERSELY ISOTROPIC, and TYPE=ANISO cannot be used if this parameter is included.

SLURRY

This parameter applies only to Abaqus/Standard analyses.

Include this parameter to define the conductivity of a slurry in a geotechnical application that models slurry transport and placement.

The conductivity of the slurry flow must be isotropic. Therefore, TYPE=ORTHO, TYPE=TRANSVERSELY ISOTROPIC, and TYPE=ANISO cannot be used if this parameter is included.

TYPE

Set TYPE=ISO (default) to define isotropic conductivity.

Set TYPE=ORTHO to define orthotropic conductivity.

Set TYPE=ANISO to define fully anisotropic conductivity.

Set TYPE=TRANSVERSELY ISOTROPIC to define transversely isotropic conductivity.
