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.
Project Settings: Opens the Project Settings dialog, which stores model setup and project meta-data information: including model default values, units and coordinate system.
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.
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
•Thumbs Up/Down - for anonymous feedback and product feature requests
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
