Sector Model Export [BETA]

The Sector Model Export [BETA] feature exports a subset of a simulation model to a standalone DATA file that can be used as input for a new simulation. It supports boundary conditions, grid refinement, model padding, and optional direct integration with an OPM Flow simulation job.

To launch the wizard, right-click on a 3D View and select Export Sector Model [BETA].

The export is configured through a step-by-step wizard with the following pages.

General Settings

Specify the name and output folder for the new sector model.

  • Sector Model Name – The base name (without extension) for the exported DATA file.
  • Export Folder – The folder where the exported files will be written. Must differ from the source case folder.
  • Source Information – Read-only display of the source case name and location on disk.

Sector Model Definition

Select which cells to include in the export.

  • Cells to Export – Choose one of the following options:
    • Visible Cells Box – IJK bounding box around currently visible cells (controlled by range and property filters in the view).
    • Active Cells Box – IJK bounding box around all active cells in the grid.
    • Visible Wells Box – IJK bounding box surrounding visible wells, extended by a configurable number of cells.
      • Well Padding – Number of extra cells to add around visible wells (default: 2).
    • Full Grid Box – The complete grid including inactive cells.
    • Manual Selection – Enter the IJK min/max coordinates directly.

The dialog shows the Total cells to export to help assess the size of the sector model.

Refinement

Optionally refine the exported grid by subdividing cells in each direction.

  • Enable Grid Refinement – Check to activate refinement.
  • Cell Count I, J, K – Number of sub-cells per original cell in each direction (range 1–10). Grid result values are not interpolated; all new sub-cells inherit the value of their parent cell.

Boundary Conditions

Configure how boundary conditions are defined for the sector model faces.

  • Boundary Condition Type – Select one of:
    • OPERNUM/OPERATER – Uses OPERNUM and OPERATER keywords to define boundary conditions. A PORV Multiplier can be set to scale the pore volume at the sector model boundary (default: 1.0e6).
    • BCCON/BCPROP – Uses BCCON and BCPROP keywords. A table of BCPROP keywords is shown, with one row per BCCON region. The number of rows is determined automatically from the maximum BCCON value found in the grid (defaulting to 6 for the six faces).

Keyword Adjustments

Control which keywords from the source DATA file are excluded from the exported sector model.

  • Keywords to Remove from Output – A list of keywords that will be stripped from the export. The default list contains: ACTION, ACTIONX, ACTIONW, BOX, UDQ. Use the Reset to Default button to restore this list.

Model Padding

Optionally extend the sector model grid in the Z direction by adding inactive padding layers above and/or below the exported cells. This can be useful to ensure that the sector model has a complete pressure column.

  • Enable Model Padding – Check to activate padding.

Upper Padding

  • Number of Z Layers – Number of padding layers to add above the model.
  • Top Depth – Depth of the top of the uppermost padding layer.
  • Porosity – Porosity value assigned to the upper padding layers (range 0–1).
  • EQUILNUM – EQUILNUM region number for the upper padding layers.

Lower Padding

  • Number of Z Layers – Number of padding layers to add below the model.
  • Bottom Depth – Depth of the bottom of the lowermost padding layer.

Grid Options

  • Minimum Layer Thickness – Minimum thickness of each padding layer (default: 0.1).
  • Fill Gaps in Z Direction – Fill any gaps between the model and the padding layers.
  • Enforce Monotonic Z-Corners – Ensures that Z-corner values are monotonically increasing.
  • Make Pillars Vertical – Forces the pillars of padding cells to be vertical.

Simulation Job Settings

Optionally create an OPM Flow simulation job from the exported sector model, and/or immediately run it.

  • Create New Simulation Job – Check to add a new OPM Flow job using the exported sector model DATA file as input.
    • Job Name – Name of the new simulation job (defaults to the sector model name).
    • Working Folder – Folder where the simulation job will store input and output files. Must differ from the export folder and the source case folder.
  • Start Simulation Job After Export – When checked, all existing OPM Flow jobs that use the exported sector model file as input will be started automatically after the export completes.

See OPM Flow Integration for more details on working with simulation jobs.
