The Initial Conditions (IC) Package dialog

The Initial Conditions (IC) Package dialog is accessed by double-clicking on the IC package under a MODFLOW 6 simulation in the Project Explorer. It contains the following sections and options:

  • Sections list – A list of sections that can be turned on or off:
    • 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 a single tab:
    • STRT – The initial (starting) head.
      • Layered – Turn on if there is more than one affected layer. Select the desired layer from the drop down in order to edit the array (if "Array" is selected from the drop-down).
      • If "Constant" is selected from the drop-down, enter a decimal value in the Constant field to be applied to all cells in the layer(s).
      • 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.
