The display options control which components of the grid are displayed. The display options can be set by selecting the Display Options command in the Display Menu. This brings up the 3D Grid Display Options dialog. Most of the items in the dialog box are toggles. If the toggle for a component of the grid is set, the component is displayed when the grid is re-drawn. The graphical attributes such as color and line style which are used to display the component can be set using the window to the left of the toggle box. The items in the dialog are as follows:
The items in the Display Options dialog are divided into several tabs: one for the general grid options and one for each of the model interfaces supported in the 3D Grid module. The items described below are for the general grid options.
The Cell Nodes item is used to display a small circle at either the cell corners or the cell centers depending on the type of the grid (mesh-centered or cell-centered).
The Cells item is used to display the edges of grid cells. The cells are drawn using the color of the material associated with each cell. Individual cells can also be temporarily hidden.
3 options are available for the cell edges:
Auto- draws the material color if faces are not displayed. Uses black or white if the faces are displayed.
Specified- used the color specified next to the cell edges
Material- displays the material color of the cell
The Inactive Cells item is used to display cells which are inactive. If this option is turned off, inactive cells are not displayed. Inactive cells must be displayed before they can be selected.
The Cell Numbers item is used to display the ID of each grid cell.
The Node Numbers item is used to display the ID of each grid node.
The Scalar Values item is used to display the scalar values of the active dataset for each node next to the node.
The IJK Indices item is used to display the ijk indices of each cell or node on the visible exterior of the grid.
The IJK Triad item is used to display a triad symbol at one of the corners of the grid showing the orientation of the ijk axes. The triad is similar to the one that appears at the bottom left of the main graphics window showing the xyz orientation.
The Layer boundaries item is used to display the boundary of active cells in each layer.
The Grid Shell item is used to display an edge for each of the edges on the "box" or hexahedron defined by the boundary of the grid. This option is useful when displaying cross sections or iso-surfaces since it provides a spatial context for the objects being displayed.
The Texture Map Image Item is used to "drape" an image over the top surface of the 3D Grid.
If the Contours item is selected, two options are provided for displaying contours: Grid Contours and Layer Contours.
The Layer Contours option is used to display contours on a horizontal 2D slice through each of the visible layers of the grid. This option is particularly appropriate for data organized on a layer-by-layer basis such as transmissivity and leakance in MODFLOW.
The Options button next to the Layer Contours option brings up the Grid Layers section of the Contour Options dialog. The Data section is used to specify which data are contoured on each layer. If the Active data setoption is selected, the active data set associated with the 3D grid is contoured. Otherwise, an input array associated with MODFLOW, MODPATH, MT3DMS, RT3D, or SEAM3D is contoured.
The Grid Contours item is used to display contours on the exterior of the visible portion of the grid using the active scalar data set for the grid.
