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:

Menu Command Description
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 >
Well (WEL) Package... Opens the Well Package dialog.
Multi-Node Well (MNW) Package... Brings up the Multi-Node Well (MNW1) Package dialog.
River (RIV) Package... Opens the MODFLOW River Package dialog.
Lake (LAK) Package...
Drain (DRN) Package...
Drain Return (DRT) Package...
General Head (GHB) Package...
Recharge (RCH) Package... Starts the MODFLOW Recharge Package dialog.
Evapotranspiration (EVT) Package...
Evapotranspiration Segment (ETS) Package...
Stream (STR) Package...
Stream (SFR2) Package...
Time Var. Head (CHD) Package...
Unsaturated Zone (UZF) Package...
HFB Package...
Convergence Options...
Parameters...
Obervations...
Parameter Estimation...
Stochastic...
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...
Toggle Barrier Creates a "no flow boundary" between two adjacent selected cells.
Cell Properties...
IFACE...
ITOP...

Obsolete Commands

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

  • LPF Package...
    Opens the flow dialog to insert hydrologic parameters. (May not be LPF)
