Structure of Blocks

FOR EACH SIMULATION

    BEGIN OPTIONS
      [BUDGET FILEOUT <budgetfile>]
      [BUDGETCSV FILEOUT <budgetcsvfile>]
      [HEAD FILEOUT <headfile>]
      [HEAD PRINT_FORMAT COLUMNS <columns> WIDTH <width> DIGITS <digits> <format>]
    END OPTIONS

FOR ANY STRESS PERIOD

    BEGIN PERIOD <iper>
      [SAVE <rtype> <ocsetting>]
      [PRINT <rtype> <ocsetting>]
    END PERIOD

Explanation of Variables

Block: OPTIONS

BUDGET keyword to specify that record corresponds to the budget.
FILEOUT keyword to specify that an output filename is expected next.
budgetfile name of the output file to write budget information.
BUDGETCSV keyword to specify that record corresponds to the budget CSV.
budgetcsvfile name of the comma-separated value (CSV) output file to write budget summary information. A budget summary record will be written to this file for each time step of the simulation.
HEAD keyword to specify that record corresponds to head.
headfile name of the output file to write head information.
PRINT_FORMAT keyword to specify format for printing to the listing file.
columns number of columns for writing data.
width width for writing each number.
digits number of digits to use for writing a number.
format write format can be EXPONENTIAL, FIXED, GENERAL, or SCIENTIFIC.

Block: PERIOD

iper integer value specifying the starting stress period number for which the data specified in the PERIOD block apply. IPER must be less than or equal to NPER in the TDIS Package and greater than zero. The IPER value assigned to a stress period block must be greater than the IPER value assigned for the previous PERIOD block. The information specified in the PERIOD block will continue to apply for all subsequent stress periods, unless the program encounters another PERIOD block.
SAVE keyword to indicate that information will be saved this stress period.
PRINT keyword to indicate that information will be printed this stress period.
rtype type of information to save or print. Can be BUDGET or HEAD.

ocsetting specifies the steps for which the data will be saved.

  ALL
  FIRST
  LAST
  FREQUENCY <frequency>
  STEPS <steps>

ALL keyword to indicate save for all time steps in period.
FIRST keyword to indicate save for first step in period. This keyword may be used in conjunction with other keywords to print or save results for multiple time steps.
LAST keyword to indicate save for last step in period. This keyword may be used in conjunction with other keywords to print or save results for multiple time steps.
frequency save at the specified time step frequency. This keyword may be used in conjunction with other keywords to print or save results for multiple time steps.
steps save for each step specified in STEPS. This keyword may be used in conjunction with other keywords to print or save results for multiple time steps.
