Data Set 12

KPER,DELT,SNAME,ISAVE,ISUMSAVE

KPER

The number of the stress period. It will be used solely to verify whether the current stress period matches the stress period read. If not a warning appears in the log file.

DELT

day

The length of the current stress period.

SNAME

The date or name for the current stress period.

DELT=0

For steady-state simulations, it should state “steady-state”, mainly for reasons of compatibility with iMOD.

DELT\(>\)0

For transient simulations it should state the date notated as: yyyymmdd; e.g. 20101231 to express the 31\({}^{th}\) of December 2010. Usage of these format is recommended strongly for compatibility with iMOD (e.g. time-series plotting).

As a consequence, all result files will show the given date/name in their names, e.g. head_[yyyymmdd]_l1.idf or bdgflf_steady-state_l8.idf.

ISAVE

This parameter defines whether output (as defined by Data Set 8) is generated for the current stress period.

-1

Result will be saved with the buffer excluded

0

No results will be saved

1

Results will be save with the buffer included

In case NMULT\(>\)1 (see Data Set 4), ISAVE will become abs(ISAVE) because the proper merging procedure will use the results in the buffer area.

ISUMSAVE (optional)

This optional parameter allows to sum all fluxes for each package per model layer. If more package entries are defined per model layers, those will be lumped into a single budget quantity.

0

Explicitly save all budget per package entry as a separate results file.

1

Sum all individual fluxes per model layer for the package entries.
