2D grid QC and connectivity settings

Neighboring nodes of a 2D grid are considered to be connected by default, but you can specify limitations to the connections between nodes when you are preparing your data for modeling. The Specify Connectivity Settings form (prepare > Post-Processing Tools > QC > Specify Connectivity Settings) is used to define these limitations and can be done so using the following steps:

  1. Open the Specify Connectivity Settings form.
  2. From the Model drop-down list, select the surface set or seismic interpretation that contains the 2D grid you want to specify connectivity settings for. All the 2D grids in this surface set or interpretation are shown underneath.
  3. Check the checkboxes of the 2D grids you want to specify connectivity for.
  4. On the Discontinuities tab, check the Discontinuity aware checkbox if you do not want neighboring nodes located on different sides of a discontinuity tri-mesh to be connected, then select the discontinuities to be taken into consideration in the Discontinuities list.
  5. On the TVDSS Difference tab, check the Enable TVDSS difference checkbox if you want to specify a maximum TVDSS difference. Neighboring nodes that are further apart than this maximum threshold value will not be connected. Enter this distance in the Maximum TVDSS difference field.
  6. On the Fault Centerlines tab, check the Select fault centerlines checkbox to select polyline sets that identify the connections that should not be connected. Select a fault gap polyline set, for example, from the Polyline sets list.
  7. Click Apply or OK to specify connectivity for your selected 2D grid or grids.
