Defining permeability in an Abaqus/Standard analysis

From the menu bar in the Edit Material dialog box, select OtherPore FluidPermeability.
(For information on displaying the Edit Material dialog box, see Creating or editing a material.)
Click the arrow to the right of the Type field, and specify the directional dependence of the permeability.
Enter a value for Specific weight of wetting liquid.
Toggle on Use temperature-dependent data to define permeability as a function of temperature.
A column labeled Temp appears in the Data table.
Enter the applicable data in the Data table:

k

Isotropic permeability of the fully saturated medium, k. (Units of LT⁻¹.)

k11, k22, and k33

Three values for orthotropic permeability, $k_{11}$ , $k_{22}$ , and $k_{33}$ . (Units of LT⁻¹.)

k11, k12, k22, k13, k23, and k33

Six values for anisotropic permeability, $k_{11}$ , $k_{12}$ , $k_{22}$ , $k_{13}$ , $k_{23}$ , and $k_{33}$ . (Units of LT⁻¹.)

Void Ratio

Void ratio, e.

Temp

Temperature.

For detailed information on how to enter data, see Entering tabular data.
If you want to define the dependence of permeability on saturation, select Saturation Dependence from the Suboptions menu. See Defining the saturation dependence of permeability” for detailed instructions.
If you want to define the dependence of permeability on velocity, select Velocity Dependence from the Suboptions menu. See Defining the velocity dependence of permeability” for detailed instructions.
Click OK to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
