*KAPPA

Optional parameters

DEPENDENCIES: Set this parameter equal to the number of field variables included in the definition of $κ_{s}$ or $κ_{p}$ . If this parameter is omitted, $κ_{s}$ or $κ_{p}$ is assumed not to depend on any field variables but may still depend on concentration and temperature. See Material Data Definition for more information.
TYPE: Set TYPE=TEMP (default) to define $κ_{s}$ (governing mass diffusion caused by temperature gradients). Set TYPE=PRESS to define $κ_{p}$ (governing mass diffusion caused by gradients of the equivalent pressure stress).

Data lines to define the Soret effect factor (TYPE=TEMP)

First line

Soret effect factor, $κ_{s}$ . (Dimensionless.)
Concentration, c.
Temperature, $θ$ .
First field variable.
Second field variable.
Etc., up to five field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than five)

Sixth field variable.
Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define $κ_{s}$ as a function of concentration, temperature, and other predefined field variables.

Data lines to define the pressure stress factor (TYPE=PRESS)

First line

Pressure stress factor, $κ_{p}$ . (Units of F⁻¹L².)
Concentration, c.
Temperature, $θ$ .
First field variable.
Second field variable.
Etc., up to five field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than five)

Sixth field variable.
Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define $κ_{p}$ as a function of concentration, temperature, and other predefined field variables.
