Planar Results (Volumetric)

The purpose of this tool is to calculate and derive the normal stress and shear stress for imaginary 2D plane(s; faults/fractures) within a 3D volume.

Up to four imaginary planes maybe defined using dip & dip direction angle pairs. This tool us useful for evaluating effects such as local fracture opening due to injection, where it is impractical to explicitly model the entire fracture set(s).
Note:
  • The results file with the 3D volume mesh and matching results is supported as inputs to calculate planar results (volumetric) tool.
  • The results types under Derive Results Based On are filtered based on the configuration in the planar_derived_resulttype_filters.txt.
  • Before launching the tool, load the model and the result files. If you launch the tool before loading the required files, the following message is displayed.
    Figure 1.
  1. Select the Planar Results (volumetric) tool from the Select GeoD Tool drop down list.
    Figure 2.
  2. Click the Load Model from the Task table.
    Figure 3.
  3. Select the Load Model and Load Results check box and browse and select the required model and results files and click Apply.
    The model and result files are loaded in the HyperView window.
  4. Click Next to move to the next step in the process.

Select inputs

  1. Click Select inputs.
    Figure 4.
    The Select inputs panel is displayed.
    Figure 5.
  2. Select the required subcase(s) check box from the Subcase table.
    Note: Once you select one or more subcases, all the other sections are activated.
  3. Click the Select All button.
    All available subcases are selected.
  4. Click the Select None button.
    All subcases are deselected.
  5. Click the Select Reverse button.
    Subcase selection is reversed.

Simulation

  1. Select the required simulation(s) from the Simulation table.
    Figure 6.

Derived Results

  1. Select the required results from the Derived Results table.
    Note: By default, the global stress with IP-Effective (Integration Point) is selected if it exists. You can select any one stress type for deriving additional results.
  2. Select the required results from the Results to Propagate table to propagate (copy) into the new h3d file.
    Figure 7.
    Note: You can propagate the results from source file to target h3d file by selecting the results from the Results to Propagate table. Uncheck the results that are not required to be propagated into the new h3d file.

Components

  1. Click the Components button.
    Extended Entity Selection window opens.
    Figure 8.
  2. Select the component by any method in the Extended Entity Selection window.
  3. Click the Displayed button adjacent to the Components button.
    Figure 9.
    The components are highlighted in the graphics area.
  4. Click All, to select all the components of the model.
  5. Click Reverse, to reverse the component selection.
  6. Click Clear Collector, to reset or clear the component selection.

Fracture Set

  1. Click Next to move to the next step in the process.
  2. Enter the values in the Dip (deg: inclined from horizontal/00) and Dip Direction (deg: clockwise from North/000) fields and press enter.
    The normal corresponding to the imaginary plane is defined in the Normal to Plane field.
    Figure 10.
  3. After defining the required inputs, click the file browser button in the Output file text field.
    A file selection window opens.
  4. Browse and select the destination folder and click Save.
  5. Click Generate H3D.
    A new H3D file will be written containing the normal and shear stresses on the imaginary planes defined. An information message is displayed.
    Figure 11.
  6. Once the H3D file is generated, a confirmation window opens.
    Figure 12.
  7. After the completion of the process, load the h3d file with planar volumetric results into HyperView window.
