Compute (Groundwater Only)

The Compute Groundwater Only option is only available if the Groundwater Method = Steady State or Transient Finite Element Analysis in Project Settings.

• The purpose of the Compute Groundwater Only option is to allow you to compute a finite element groundwater seepage analysis, without computing the finite element stress analysis.
• For example, you may wish to test various groundwater conditions, or verify that you have setup the groundwater boundary conditions correctly for a model, before you proceed to the stress analysis. This can be particularly useful for complex, staged models, where the compute time may be significant, and it is necessary to verify the groundwater results before proceeding to the stress analysis. It can also be used if you are only analyzing a groundwater model, and do not require stress analysis results.

The Compute Groundwater Only option is available in the toolbar or the Compute menu. It is only enabled when the finite element mesh is generated.

Compute Groundwater and Stress Analysis

It should be noted that the groundwater seepage analysis is automatically computed when you select the main Compute . That is, whenever you compute a stress analysis with RS3, the groundwater seepage analysis is automatically computed before the stress analysis.

The Compute Groundwater Only option does NOT have to be selected. It is entirely optional, and is available for the purpose described above.
