Advanced Stress Settings

In the Field Stress dialog, you may configure advanced settings relating to the stress analysis, by selecting the Advanced button. In the Advanced Settings dialog you may define:

Rock mass Young's modulus

Rock mass Poisson's ratio

Matrix solution technique

Element type

Number of elements

Number of joint sample points

Number of intervals for contours

Apply pressures as boundary conditions - if your Unwedge model includes Pressure (the Add Pressure option) then you can choose to include Pressure(s) as boundary conditions in the boundary element stress analysis. By default this checkbox is selected. This means that the Pressure(s) will affect the results of the Stress analysis. If you do not want Pressure(s) included in the boundary element stress analysis, then clear this checkbox.

The boundary element stress analysis used in Unwedge, is based on the analysis engine used in the Rocscience program Examine2D. For more information about Examine2D, you can click the following link:

The Examine2D reference manual can be downloaded, which contains information on the various analysis parameters.
