Defining the saturation dependence of permeability

You can define the dependence of permeability, k¯, on saturation, s, by specifying ks. Abaqus/Standard assumes by default that ks=s3 for s<1.0; ks=1.0 for s≥1.0. The tabular definition of ks⁢(s) must specify ks=1.0 for s≥1.0.

Context:

For more information, see Permeability.

  1. Define permeability, as described in Defining permeability in an Abaqus/Standard analysis.”

  2. From the Suboptions menu in the Edit Material dialog box, select Saturation Dependence.

    A Suboption Editor appears.

  3. Enter the following data in the Data table:

    k_s

    The dependence of permeability on saturation of the wetting liquid.

    Saturation

    The fluid saturation (s=1 for a fully saturated medium; s=0 for a completely dry medium).

    For detailed information on how to enter data, see Entering tabular data.

  4. Click OK to return to the Edit Material dialog box.
