Frictional Fault Boundaries

With the Frictional Fault Boundaries tool (1D Model > Horizontal Stress) you set the lower and upper limits for the horizontal stress profiles calculated using the Effective Stress Ratio method. With the tool you set the stage for the user to define ESR profile. Following the boundaries you ensure the values are not falling out the frictional stress equilibrium.

On the form, check the checkbox adjacent to the Sliding Friction Coefficient to the specify the input and enter the value in the field. Optionally, you can use the slider to set the value. The range of coefficient value must be within 0 and 1.

Based on the sliding friction coefficient value, the Lower limit and Upper limit values for the effective stress ratio are generated (read-only) below. On the Horizontal Stress view, this calculated range is displayed with a shaded background in the track of 'Shmin, Effective Stress Ratio' and 'SHmax, Effective Stress Ratio'. Lower limit is shown with a dotted blue color and the upper limit with dotted red color.
