This option edits cells that have masks. When selected, Vertical Cell Face Blocking form appears as shown in Figure 4.

On the Vertical Cell Face Blocking form as shown in Figure 4, it shows all the grid cells of the domain, which has masks of the domain on the List of Cells frame. I, J, and L indices of the cell are shown in the Cell Indices frame. Initial conditions of the cell, including bottom elevation, water depth, water surface elevation, are shown in the Initial Conditions frame, these fields are not editable. The user can edit the cell's mask by changing the mask's properties on the Current Cell frame.  In this case, the cell (L=97) has masks on the west and south faces, so boxes for Completely Block Mask of the two faces are checked (see Figure 4)

In case the user wants to change a mask from completely blocking to partially blocking, the box needs to be unchecked. For example, we will uncheck the box for the west face. Then the Floating option can be checked or unchecked, values for Draft, Bottom Sill can be entered as shown in Figure 5. Click the Close button to complete setting the masks for the grid cell.
