GMS:MODFLOW Commands

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.
