< Appearance (Fig. 3.62) allows you to change the visibility and appearance color of each
simulated component. A simulated component is visible if the corresponding Visibility
checkbox is checked. To select a new color, click on the colored cell (a button appears),
then click on the button and select a color from a Color dialog box.

< Coordinate System is used to define the extent and location of the area of interest (the
worksheet) and to define location and orientation of the model grid.
As illustrated in Fig. 3.63, the worksheet is a “window” to the real-world, your model
grid is placed within the worksheet. The extent and location of the worksheet are defined by
specifying the (real-world) coordinates of its lower-left and upper-right corners; i.e., by the
coordinates (X , Y ) and (X , Y ) as shown in Fig. 3.63 and Fig. 3.64. The location and
1 1 2 2
orientation of the model grid are defined by the coordinates (X , Y ) of its left-upper corner
0 0
and a rotation angle. The rotation angle is expressed in degrees and is measured
counterclockwise from the positive x-direction.
< Contours: The Data Editor displays contours based on the cell data. The Contours tab
allows you to control the display of the contour levels, labels and colors. The options of this
tab are listed below.
- Visible: Contours are visible if this box is checked.
- Display contour lines: Contour lines (and labels) are displayed if this box is checked.
- Fill contours: Checking this box causes the space between contour lines to be filled with
the color defined in the contour level table.
- Orient label uphill: If this box is checked, the contour labels are displayed so that they
are always oriented uphill (i.e., oriented to places with higher cell values).
