By default, all print options are set to true at the beginning of a run, with the exception of -alkalinity . Once set by the keyword data block PRINT , options remain in effect until the end of the run or until changed in another PRINT data block.
Unlike most PHREEQC input, the order in which the identifiers are entered is important when using the -reset identifier. For the identifiers controlled by -reset , any identifier set before -reset in the data block will be reset when -reset is encountered. Thus, -reset should be the first identifier in the data block. Using -reset false will eliminate all printing to the output file except the echoing of the input file and the printing of warning and error messages.
For long TRANSPORT and ADVECTION calculations with KINETICS, printing the status line [ -status true (default)] may cause a significant increase in run time. This has been the case on some Macintosh systems. If printing to the screen is unbuffered, the program must wait for the status line to be written before continuing calculations, which slows overall execution time. In this case, setting -status false may speed up run times. Alternatively, the time interval for updating the status line may be set to be an integer number of milliseconds. For example, -status 500 will suspend any printout to the status line for 500 milliseconds while computations continue unhindered. With a set time interval, the on-screen status line may not show the actual final status of the program when it reports “Done”.
The identifiers -species and -saturation_indices control the longest output data blocks in the output file and are the most likely to be selectively excluded from long computer runs. Use of the -censor_species identifier also will decrease the size of the output file and simplify the results. If transport calculations are made, the output file could become very large unless some or all of the output is excluded though the PRINT data block ( -reset false ). Alternatively, the output in transport calculations may be limited by using the -print_cells and -print_frequency identifiers in the ADVECTION and TRANSPORT data block. For transport calculations, the SELECTED_OUTPUT data block usually is used to produce a compact file of selected results.
The keyword PRINT is used in example problems 6, 10, 12, 13, 14, 15, 19, 20, and 21.
ADVECTION: -print_cells and -print_frequency , SELECTED_OUTPUT, TRANSPORT: -print_cells and -print_frequency , USER_GRAPH, USER_PRINT, and USER_PUNCH.
