Cell Index
This Viewing Opt displays the EFDC indexes of I & J and the linear index "L" on a cell map based on LXLY coordinates. The data posting label format is used to display the indexes.
Select Cell Index for Parameter, in the Cell Indices Options as shown in Model Grid (2DH View)#Figure 10, the user can select options for displaying.
No Labels: if this option is selected, there is no IJ or L index displayed on the 2DH View.
2: if this option is selected, I and J index will be displayed
Show L's: if this option is selected, L index will be displayed
Show East: if this option is selected, the lines crossing cells that are facing to the East are displayed
Show South: if this option is selected, the lines crossing cells that are facing to the South are displayed
The I Skip and J Skip fields can be used to reduce the frequency of labeling.
Finally, the user clicks the Add button to add the Cell Indices layer to the Layer Control. The cell indices are displayed as shown in Model Grid (2DH View)#Figure 11.
