You can also look at specific parts of the grid by choosing the boundaries you wish to view under Surfaces (click to select and click again to deselect a specific boundary). Click Display again when you have selected your boundaries. For example, the wall, outlet, and centerline boundaries have been selected in the following view:

For convenience, the Image Removed button next to Surfaces selects all of the boundaries while the Image Removed deselects all of the boundaries at once.
Close the Grid Display Window when you are done.
