The following sections describe the various menu and toolbar options in Visual MODFLOW Flex.
The File menu provides access to standard operations such as open, save, save as, and close project. The file Menu can also be used to import data from external sources and modify project settings. You will find the last few models you have opened so you can quickly re-open them.
New Project <CTRL+N>: Opens the create new project setup dialog.
Open Project <CRTL+O>: Opens an existing project. Note: only one project can be open in Flex at a time.
Import Project <CTRL+I>: Imports a Visual MODFLOW Classic (*.vmf) file.
Close: Closes the active project
Save Project <CTRL+S>: Saves the active project to its current location.
Save Project As <F12>: Saves the active project in a selected location.
Import Data <CRTL-D>: Opens the Import Data dialog to add external data to your project.
Recent Project List: A list of the most recently saved projects will be shown. Selecting any of the projects in the list will close any active project (upon user confirmation) and open the selected project.
Exit <Alt+F4>: Exits Flex - you will be prompted to save your project if one is open.
The View menu allows you to turn on or off the Data and Model Explorer <F11> and the Workflow tree <F4>.
The Tools menu provides the following options:
Free Memory: allows you to free up the memory usage if you have been running a number of high-demand, 3D visualization operations
3D Viewer Settings
By default, Visual MODFLOW Flex will attempt to use the vendor-provided driver included with your graphics acceleration hardware. If problems are encountered with the vendor provided drivers, e.g., poor on-screen display/performance, then Visual MODFLOW Flex provides the option to use the Microsoft Driver for OpenGL.

Depending on the size of your model, Visual MODFLOW Flex may run very slowly during rotations or when 3D Numerical Gridded data objects are moved in the 3D Viewer (eg. MODFLOW Heads, Drawdown, Properties, or Transport Concentrations). In this situation, the virtual data grid option may be used to increase the speed of the data processing and image rendering. It can be used to set up a uniformly spaced grid with a specified number of rows and columns.
The virtual data grid option will interpolate the data from the model to the uniformly spaced virtual grid. This allows a smaller amount of information to be processed much faster. However, this also results in a loss of resolution of the data, and some local scale minimum and maximum values may be missed.
If you are experiencing performance issues, try choosing the "Low" option. The number presented in parentheses is the number of cells used along the X and Y axis for the virtual data grid.
Surface Visualization Quality
This parameter controls the visualization quality and speed of surface data objects for the 3D viewer. This parameter can be used when you want to display surfaces with a large grid size (eg. 500 x 500 or greater). Similar to the Virtual Data Grid option above, Surfaces will be re-sampled to the defined grid size (where the number in parentheses represents the uniform number of rows/columns).
This setting provides two options for displaying points in 3D Viewer: Basic and Advanced. If the Basic option is selected, 3D Viewer will render the point shapes in the 3D Viewer. On some computers this option may hinder the performance of the 3D Viewer. If the Advanced option is selected, 3D Viewer will use bitmap images to display the points. If you are experiencing performance issues display points in 3D Viewer, the Advanced option should be selected.
Note: The Basic option only supports cube and sphere symbols for displaying points.
By default, Visual MODFLOW Flex collects anonymous usage statistics. You can opt out by deselecting this option. For more information about our data collection, please see here.
Restore System Settings
Use this option to reset the factory style settings. If you open a project from Hydro GeoBuilder, some of the new display features may not immediately show up. Please select Tools / Restore System Settings. Then save the project, close, and reload and this should correct the problem.
Visual MODFLOW Flex provides an option to use Project-wide Color Palettes. This is useful when you have multiple data objects that are rendering the same attribute (eg. heads from different model runs, conductivity distributions), and you want to make qualitative comparisons between these. This is challenging when each data object has its own min and max values and are colored based on this. However, it becomes much easier when these data objects all read from a common color palette.
The Project Color Palette settings allow you to set the min/max values for various attributes; these can then be used for various data objects and viewers throughout the project.
To enable the Project Color Palette option for a specific data object, this must be enabled in the Color by Attribute page; see Color by Attribute for more details.
Allows you to create a new Numerical Model workflow or Conceptual Model workflow or open existing workflows. When you select the appropriate item, the associated workflow window will load.
Allows you to creates a new 2D, 3D, or time series viewer of the active data object selected in the Data Viewer/Model Explorer or reset the active view to the default extents.
Provides links to help topics, webhelp, and online resources. The Just-In-Time Help will display a small help panel below most steps in the workflow window.
Help Topics (F1): opens the built-in help documentation including tutorials and getting started guides
Web Help: opens the online-help documentation
Release Notes: opens the online documentation for the changes associated with each version
Online Support and Resources: opens the online page for accessing technical resources and contact information for technical support
Checks for Updates: calls out to Waterloo Hydrogeologic's webpage to see if updates are available.
Show Error Log: opens the Visual MODFLOW error log, which can be useful in helping technical support diagnose and pinpoint problems, if they arise.
Show System Information: opens a text file with system configuration information, which can be useful in helping technical support diagnose problems, if they arise.
About... launches the About Screen, which shows the version and build you are using along with your registration details (name, company, serial number)
Licensing Help will load the online help for working with licensing.

Below the main menu, there are two toolbars:
The toolbar in the first row contains application/project level options; from left to right, these options are:
•Show/Hide the Model Explorer (and Data tab)
•Show/Hide the Workflow Tree
The toolbar in the second row contains options for adjusting the Data tab and Model Explorer; from left to right, these options are:
•Combine Data tab and Model Explorer into one view, separated by tabs
•Separate the Data tab and Model Explorer into one frame above the other (factory default setting)
•Collapse All (levels of the tree)
•Collapse to Selected item on the Model Explorer
•Dock Model Explorer to the left side of the window
•Dock Model Explorer to the right side of the window
