1. Convert geometry to a UGrid, selecting complex stratigraphy during conversion.
  1. Select the Feature Objects | Map → UGrid... menu command.
  2. In the Map → UGrid dialog, enter parameters for the UGrid.
    • Quadtree UGrids
    • Voronoi UGrids
    • VTK Unstructured Grids
2. Use borehole data to create a 3D UGrid.
  1. Select the Boreholes | Horizons → UGrid… menu command.
  2. Use the Horizons to UGrid wizard.
3. Create a MODFLOW-USG model.
1. Create a MODFLOW simulation.
  1. Select the 3D Grid Icon.svg 3D grid or UGrid Module Icon.svg UGrid in the the Project Explorer.
  2. Select the MODFLOW | New SImulation... command.
2. Set up the MODFLOW Global/Basic Package options.
  1. If necessary, select the MODFLOW | Global Options... command.
  2. In the MODFLOW Global/Basic Package dialog, set all the appropriate parameters:
  • Arrays
    • IBOUND
    • Starting heads
    • Top and bottom elevations
    • Confining beds
    • Porosity
4. Map to MODFLOW.
  1. Select the conceptual model Conceptual Model Icon.svg.
  2. Select Feature Objects | Map → MODFLOW Map to MODFLOW Macro.svg.
  3. Select the appropriate options in the Map → Model dialog.
5. Run MODFLOW.
  1. Save Save Macro.svg the project.
  2. Run MODFLOW Run MODFLOW Macro.svg.
