The Zone File dialog

The ZONE FILE dialog is accessed by double-clicking on the ZONE FILE package under a MODFLOW 6 simulation in the Project Explorer. It contains the following sections and options:

    • Comments – Turn on to make the Comments section visible.
    • GridData – Turn on to make the GridData section visible. This section is on by default.
  • Comments section – Enter general alphanumeric comments. Comments entered here get written at the top of the file, preceded by a '#' symbol.
  • GridData section – Contains one tab (IZONE):
      • Layered – Provides an array for each layer of the grid.
      • If "Constant" is selected from the drop-down, enter a decimal value in the Constant field to be applied to all cells in the top model layer.
      • If "Array" is selected from the drop-down, a user-editable array appears below the drop-down. Enter a decimal Factor value to the right of the drop-down. The individual elements of the array are multiplied by the factor value after they are read.
      • Dataset to Array... – Click to open the Select Dataset dialog. Select the desired database(s) in this dialog.
