The Display Options dialog showing the 3D Grid dialog.

The properties of all 3D grid data that GMS displays on the screen can be controlled through the 3D Grid tab of the Display Options dialog. This dialog is opened by right-clicking on the 3D Grid Data 3D Grid Folder.svg entry in the Project Explorer and selecting the Display Options command. It can also be accessed from the from the Display menu or the Display Options Display Options Macro.svg macro. The following table describes the display options available for the 3D Grid module.


Display Option Description
Nodes Displays grid node dots on the cell corners for both cell-centered and mesh-centered Grid Types. Node display can be adjusted in the Point Properties dialog accessed through the point icon next to Nodes.
Cell edges Displays the edges of grid cells. The cells are either drawn using the default cell color or the color of the material associated with each cell.

In addition to turning the display of cells on or off, GMS can temporarily hide grid cells.

The color of the cell edges can be adjusted according to the following options:

  1. Auto – Draws the material color if faces are not displayed. Uses black or white if the faces are displayed. The thickness and the line style can still be adjusted in the Line Properties dialog accessed through the gray box next to Element edges.
  2. Specified – Uses the color and style specified next to Cell edges.
  3. Material – Displays the material color of the cell with the thickness and line style options of the Cell edges Line Properties dialog.
Cell faces Causes the faces of the grid cells to be drawn as filled polygons. They are filled with the material color.
Inactive cells Displays cells which are inactive. Inactive cells must be displayed before they can be selected. If inactive cells are not displaying after this option has been selected, make sure the ortho view is turned on. It is turned on by selecting the Ortho View Macro.svg Ortho Mode macro. Also ensure that view is in plan view using the Plan View Macro.svg Plan View macro.
Determine activity using Sets the criteria for determining which cells to display as active or inactive.

Options for determining cell activity displays include:

  1. Data Set Activity – Cells are considered inactive if they are inactive in the current active dataset. Therefore, selecting a new dataset in the Project Explorer changes the activity of cells and influences how they are displayed.
  2. MODFLOW IBOUND – If dataset flags are not currently present in the active dataset, and a MODFLOW simulation is currently in memory, the active/inactive status of cells will be determined by the MODFLOW IBOUND array. If there is no MODFLOW in the current project, then selecting this option might not change the display.
  3. MT3D ICBUND – If dataset flags are not currently present in the active dataset, and a MODFLOW simulation with MT3D is currently in memory, the active/inactive status of cells will be determined by the MT3D ICBUND array. If there is no MT3D in the current project, then selecting this option might not change the display.
  4. None – Displays active cells according to current active dataset like in the "Data Set Activity" option. Disables the option to turn the Inactive Cells display on or off. If Inactive Cells was on, then it will remain on when "None" is selected.
Named layer ranges legend A legend showing the material and named layer ranges can be turned on.
Cell numbers Displays the ID of each grid cell.
Node numbers Displays the ID of each grid node.
Scalar values Displays the scalar values of the active dataset for each node next to the node.
IJK indices Displays the ijk indices of each cell or node.
IJK triad Displays a symbol at one of the corners of the grid showing the orientation of the ijk axes.
True layer display Displays vertical variations in stratigraphy as defined by the Top Elevation and Bottom Elevation arrays in MODFLOW. In Ortho Mode, the variations in stratigraphy are visible from the side views. In general mode, the variations are visible from any angle besides Plan View. The display of variations in stratigraphy will vary between general mode and ortho mode. True layer display enables the display of the Water table feature in MODFLOW.
Layer borders Displays a solid line around the perimeter of the grid layers.
Grid shell Displays a solid cube around the extents of the grid. Displaying the boundary is useful when isosurfaces are being displayed with the cell edges turned off.
Texture map image Used to "drape" an image over the surface of the 3D Grid.
Synch ortho levels with all grids When using MODFLOW-LGR with parent and child grids, GMS will find and display the appropriate level for all grids when the level of the active grid changes. Otherwise only the active grid level will change.
Contours Most of the objects supported by GMS can be contoured by turning on the Contour Options in the Display Options dialog. When an object is contoured, the values associated with the active dataset for the object are used to generate the contours.

In the 3D Grid display options tab, use the Layer contours option to display on the surfaces of grid layers. Use the Grid contours option for the contours to display not only on the horizontal surfaces but along the vertical sides of the grid elements as well.

Vectors If the Vectors item in the Display Options dialog is selected for an object (TIN, Grid, or Mesh), vector plots can be generated using the active vector dataset for the object. One vector is placed at each node, cell, or vertex.
Isosurfaces If the Isosurfaces item in the Display Options dialog is selected for an object (3D grid or 3D mesh), isosurfaces will be generated. An isosurface is the 3D equivalent of a contour line. While a contour line is a line of constant value extracted from a surface, an isosurface is a surface of constant value extracted from a 3D dataset.
Specified Dataset Allows displaying the contours of a second dataset that is specified by the user. Use the Select Dataset command to open a Select Dataset dialog and choose the dataset desired for display. Separate contouring options can be set for the active and the specified datasets.
