| ==Model Executables==
| |
| [[File:PreferencesModEx.png|thumb|450 px|The ''Preferences'' dialog showing the ''Models'' options]]
| |
| The ''Models'' page allows specifying 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 [[GMS:Numerical Models|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 [[GMS:Stochastic Modeling|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 [[GMS:Preferences#MODFLOW|MODFLOW preferences]] for an option to turn on or off the parallel version.

| ==MODFLOW==
| |
| [[File:PreferencesMODFLOW.png|thumb|450 px|The ''Preferences'' dialog showing the ''MODFLOW'' tab.]]
| |
| 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 [[GMS:Custom Run MODFLOW|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.

| |
| *''Draw Order''
| |
| ::Allows determining the vertical location of objects when being drawn.
| |
| *''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.

| ==Program Mode==
| |
| [[File:PreferencesProgMode.png|thumb|400 px|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:
| |
| ::#Hiding of tools and modules not in use
| |
| ::#SEEP2D model automatically initialized from conceptual model
| |
| ::#SEEP2D boundary conditions automatically mapped from conceptual model (no need to run Map → SEEP2D)
| |
| ::#Easily create all coverage types in one step
| |
| ::#Feature object types automatically assigned based on coverage attributes
| |
| ::#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:
| |
| <!-- Please do not change the following bullet points. These are exact quotes from the error messages. Thanks! -->
| |
| :*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
| |
| ::[[GMS:T-PROGS|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.

| [[File:GMSunits.png|thumb|250 px|The ''Units'' dialog.]]
| |
| When building a ground water model, it is important to ensure that consistent units are used when entering model parameters. To simplify the management of model units, define the units for length, time, mass, force, and concentration in the ''Units'' dialog. A units label is placed next to each of the input fields in all the model dialogs in GMS where the units are known. For example, the units for hydraulic conductivity are length / time. If the length units are defined as "m" (meters) and the time units are defined as "d" (days) in the ''Units'' dialog, then the units string next to the hydraulic conductivity input field would be "m/d".
| |
| | |
| ''Length'' units are specified in the [[Projections|''Display Projection'']] dialog which is accessed by clicking on the [[File:Dot dot dot button.png|28px]] button to the right.
| |
| | |
| Concentration units can be defined separately, and potentially inconsistently with, mass and length units. This allows for more flexibility but can also lead to confusion so use care when selecting concentration units.
| |
| | |
| The ''Units'' dialog is accessed by using the '''Units...''' command in the ''Edit'' menu.
| |
| | |
| ==Unit Conversion==
| |
| | |
| Generally speaking, GMS does not convert quantities from one system of units to another. GMS only displays the chosen units to help in checking consistency. However, in a few places, GMS will use the currently defined units in its calculations. These include:
| |
| | |
| * in the [[GMS:FEMWATER_Model_Input#Fluid_Properties|''FEMWATER Fluid Properties'']] dialog,
| |
| * in the [[GMS:FEMWATER_Model_Input#Curve_Generator|''Curve Generator'']] dialog,
| |
| * when calculating the stream stage constant when saving MODFLOW, and
| |
| * in the [[GMS:Toolbars#Static_Tool_Palette|'''Measure''']] tool.
