The Preference dialog showing the General tab

The Edit | Preferences command brings up the Preferences dialog.

General

The General tab has all the of the general options in GMS.

  • Show welcome dialog on startup
  • Check for newer version on startup
  • Confirm Deletions – Whenever a set of selected objects is about to be deleted, the user can choose to be prompted to confirm the deletion. This is meant to ensure that objects are not deleted accidentally.
  • Ask for file editor program

Sections:

  • File compression – When saving XMDF files, a user can use compression. The compression factor can be specified.
  • Project Explorer – Allows the user to modify preferences related to the Project Explorer.
  • Change Module when tree selection changes – Changes the current module when a item is selected in the Project Explorer. This option is on by default.
  • Scroll Project Explorer when changing module – Ensures the visibility of the tree item objects in a module when the module is changed.
  • Synchronize active dataset and Z elevations for TINs, 2D Meshes, 2D Grids, and 2D Scatter Sets
  • Contouring – Allows the user to enter a filled contour tolerance.
  • North arrow path – Specify the path to the folder containing the North Arrows.
  • Help – Options to use local help or online help. Online help is the default option.

Buttons at the bottom:

  • Help... – Specify to use either a local help file or the online help file when clicking on the Help button in any dialog.
  • Restore Factory Preferences – Reverts all settings to the factory defaults.
  • OK – Accepts the settings as selected and entered and closes the Preferences dialog.
  • Cancel – Close the Preferences dialog without saving any changes to the settings.

Model Executables

The Models page allows the user to specify the location of model executables, as well as the option to use the Model Wrapper.

  • Model Wrapper

GMS is a pre- and post-processor for Numerical Models. Most of these numerical models are run externally in the DOS environment. The default option is to use the Model Wrapper. The Model Wrapper "wraps" itself around the same DOS executables and gives more model feedback including graphs and tables. The Model Wrapper includes a toggle box in the bottom left that, when checked and after exiting the Model Wrapper, GMS will automatically read in the results of the solution. This toggle will only be checked by default if the model converged. The option to use the Model Wrapper or the old DOS view is included in the Preferences dialog. Certain models, including Stochastic and inverse modeling, can only be run using the Model Wrapper.

Parallel versions of MODFLOW-2000, MODFLOW-2005, and SEAWAT are shipped with GMS to run simulations. Beginning with version 8, GMS ships parallel versions where the SAMG solver has been parallelized. Even when this option is on, when running Parallel PEST with MODFLOW the serial (non-parallel) version of MODFLOW will be used since the Parallel PEST will use all of the available cores on the computer with the serial version. Also see MODFLOW preferences for an option to turn on or off the parallel version.

The Preferences dialog showing the Models options

MODFLOW

The MODFLOW page has options related to the MODFLOW interface in GMS.

  • Reverse mini-grid increment

The default functionality of the arrows next to the edit field on the mini-grid tool bar is for the up arrow to increase the layer number and for the down arrow to decrease the layer number. This option changes direction of the arrows so that down will increase the layer number and up will decrease the layer number.

  • Compress MODFLOW H5 files

This option will force the H5 files saved with MODFLOW to be compressed. Generally this option should be turned on.

  • Create h5 copy of head solution

Turning on this option can speed up reading the MODFLOW head solution especially when there are a large number of stress periods. When this option is on, GMS writes an HDF5 copy of the MODFLOW head solution upon reading it the first time. The following times GMS reads the head solution, it doesn't take as much time.

  • Create cell summary text file

A text file is created when reading the MODFLOW head file that provides a summary of the the number of active, inactive, dry, and flooded cells at each output time of the simulation. The text file is added to the MODFLOW solution and can be opened from the Project Explorer.

  • Save copy of MODFLOW simulation in native text format

This option will create an additional MODFLOW directory when the GMS project is saved that will contain native MODFLOW text files of the MODFLOW simulation. The new directory will be named as follows myProject_MODFLOW_text. There are three additional preferences with this option: all arrays be written internally in the MODFLOW files (default option), all arrays are external from the MODFLOW files, or all arrays are external and are placed in a directory named arrays. External arrays are placed in their own text files and are named as follows myProject_array_PACKAGE_VARIABLE_LAYERorSP. For example the ibound array for layer 1 would have the following name myProject_array_BAS_IBOUND_1.txt. The recharge array for stress period 3 would have the following name myProject_array_RCH_RECH_3.txt.

  • Use custom Run dialog when running MODFLOW

This option will bring up the Custom Run MODFLOW dialog when the MODFLOW | Run MODFLOW menu command is selected.

  • Default version of MODFLOW to run

Allows selecting the version of MODFLOW to be used as a default when GMS is started.

  • Double precision

When this option is on, GMS will use the double precision version of MODFLOW to run simulations. By default this option is off and GMS uses the single precision version of MODFLOW.

  • Parallel (not used by Parallel PEST)

When this option is on, GMS will use the parallel version of MODFLOW to run simulations. Beginning with version 8, GMS ships parallel versions of MODFLOW where the SAMG solver has been parallelized. Even when this option is on, Parallel PEST will use the serial (non-parallel) version of MODFLOW since the Parallel PEST will use all of the available cores on the computer.

The Preferences dialog showing the MODFLOW tab.

Images / CAD

  • Bitmap Scale Factor

When the copy command is selected, a bitmap image of the screen is placed on the clipboard. The scale factor can be used to increase :or decrease the resolution of the bitmap. This scale factor also applies when saving the image as a bitmap.

  • CAD Symbol Size

The size of the CAD symbol display can be specified.

The Preferences dialog showing the Images / CAD tab

Printing

Specifies scaling points, lines, and fonts while printing.

The Preferences dialog showing the Printing tab

Program Mode

The Preferences dialog showing the Program Mode tab.

GMS has the option of changing the "mode" or "skin" that GMS is running. The purpose of the mode is to simplify the items available in the interface.

Available Modes

  • GMS

This is the default mode.

  • GMS 2D

GMS 2D is for only using GMS to do seepage and slope stability. In GMS 2D mode the only tools that are available are the 2D mesh and the Map. There are several changes to the GMS interface when in this mode, including:

  1. Hiding of tools and modules not in use
  2. SEEP2D model automatically initialized from conceptual model
  3. SEEP2D boundary conditions automatically mapped from conceptual model (no need to run Map → SEEP2D)
  4. Easily create all coverage types in one step
  5. Feature object types automatically assigned based on coverage attributes
  6. Allow only one conceptual model

When starting up in GMS 2D mode, a New Project dialog will appear. The following errors may also appear when opening some project files. These errors may state any of the following:

  • Your project file contained more than one conceptual model. This version of GMS only supports one SEEP2D/UTEXAS conceptual model. The first encountered SEEP2D/UTEXAS conceptual model has been preserved and all other conceptual models have been removed from the project.
  • Error. This requires the "MODFLOW" component. Your GMS license does not include this component. Contact your vendor if you would like to enable this feature.
  • The project that you are reading does not have a SEEP2D/UTEXAS conceptual model. The project can not be loaded into this version of GMS.
  • GMS Site

GMS Site is for only using tools for site characterization. As such the tools available in this mode are TINs, Boreholes, Solids, 2D Scatter, and Map. These tools can be used to construct solid models of stratigraphy.

  • TPROGS

T-PROGS is used to perform transition probability geostatistics on borehole data.

Caveats

When GMS is running in a particular mode then only data associated with the available tools will be read into GMS. For example, if having a GMS project file that contains a 3D Grid, and running in "GMS 2D" mode then when reading in the project file a message will appear stating that GMS is not enabled to read in 3D Grid data. The only data that will read into GMS in "GMS 2D" mode is data associate with the 2D Mesh and the Map.

Map

The Preferences dialog showing the Map tab.

Gives the option to automatically perform the Map→SEEP2D command.

    The 2D Mesh tab in as the following options:

    • Interpolate for default z on interior

    Default z (ft)

    • Assign default z-value
    • Prompt for z-value
    • Insert nodes into triangulated mesh
    • Check for coincident nodes
    • Retriangulate voids when deleting

    Thin triangle aspect ratio

    For more information, see 2D Mesh Settings.

    Graphics

    • Ask which library to use if system does not support all functionality
    • Autoselect the software library if system does support all functionality
    • Always use system library (may not support all features)
    • Always use software library (may be slower)
    • Use smooth fonts: anti-alias fonts
    • Invert mouse wheel zoom: changes direction of the zoom with the mouse wheel
