The Temporal Discretization (TDIS) Package dialog is accessed by double-clicking on the TDIS 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.
    • Options – Turn on to make the Options section visible.

Right-clicking on the row number in the spreadsheet gives a menu that allows inserting, deleting, copying, or pasting a row. The columns in the spreadsheet include:
    • PERLEN – The length of a stress period. The default value is "1.0".
    • NSTP – The number of time steps in a stress period. The default value is "1".
    • TSMULT – The multiplier for the length of successive time steps. The default value is "1.0".
    • ENDDATE – The end date for that period. This field is not directly user-editable, but will automatically change if the PERLEN value is changed.
