### Property Initialization

The following FISH routine initializes the bulk modulus of a material as a function of the current mean effective stress. The function used for the purposes of this example is in the form:

Where a and b are constants and p is the mean pressure in the zone.

This is a particularly simple example, for the purposes of illustration.
