The MODFLOW menu becomes active once the MODFLOW model has been built in GMS. The menu has two submenus: Optional Packages and Advanced. The commands in the MODFLOW menu are listed below:

  • New Simulation...
    Creates a new MODFLOW simulation and brings up the Global Options/Basic Package dialog. If a simulation exists then the current one will be deleted and a new one will be made.
  • Delete Simulation...
    Deletes the current MODFLOW simulation.
  • Check Simulation...
    Brings up the Model Checker dialog. This generates a list of possible errors and warning messages in the top scrolling window.
  • Run MODFLOW...
    Initiates the MODFLOW executable. GMS will ask if you would like to save your work before running the executable.
  • Read Solution...
    Opens a window for the user to search for a previous MODFLOW solution.
  • Flow Budget...
    Shows the model's flow budget as one zone (default) or multiple user defined zones.
  • Global Options...
    Opens the MODFLOW Global/Basic Package dialog to set up a MODFLOW simulation.
  • BCF – Block Centered Flow...
    Opens the MODFLOW Block Centered Flow Package dialog. See BCF Package to learn more.
  • PCG2 – Pre. Conj.-Gradient Solver...
    Opens the MODFLOW PCG2 Package solver dialog for the selected solver. (May not be PCG2)
  • OC – Output Control...
    Opens an output dialog for the user to chose what comes out of a MODFLOW run.
  • Optional Packages >
  • Parameters...
    Brings up a Parameters dialog. Options available in this dialog will vary. To learn more, see Standard MODFLOW Parameters.
  • Obervations... ||
  • Parameter Estimation...
    Becomes available when Stochastic or Stochastic Inverse is selected as the Run Options in the MODFLOW Global/Basic Package dialog. To learn more, see Parameter Estimation Dialog.
  • Stochastic...
    Becomes available when Stochastic or Stochastic Inverse is selected as the Run Options in the MODFLOW Global/Basic Package dialog. The command brings up the Stochastic Options dialog. See Stochastic Options Dialog for more information.
  • Advanced >
    • Export Native MF2K Text...
      Creates native MODFLOW files from existing GMS MODFLOW-with-hdf5 files.
    • Display Options...
      Opens the Display Options dialog showing the MODFLOW tab.
    • Sources/Sinks...
      Launches the MODFLOW Source/Sinks dialog. For more information see, MODFLOW Source/Sink Dialog.
    • Toggle Barrier
      Creates a "no flow boundary" between two adjacent selected cells.
    • Cell Properties...
      Brings up the 3D Grid Cell Properties dialog. For more information, see [GMS:Cell Properties|Cell Properties]].
    • IFACE...
      Opens the MODPATH IFACE dialog.
    • ITOP...
      Brings up the MODPATH ITOP dialog.


Obsolete Commands

The following commands have been removed from the MODFLOW menu the most recent versions of GMS.

  • LPF Package...
    Opens the flow dialog to insert hydrologic parameters. (May not be LPF)
  • Convergence Options...
    See the PEST-ASP... command.
