6000 Stress Periods

Recommended Posts

Is there a relatively easy way to set up 6000 stress periods without actually having to touch each stress period. It is a situation where I have a well that has high level kick on and low level kick off floats that I want to simulate, so i want to repeat the same sequence. Essentially 45 seconds on and 6.5 minutes off.

Thanks,

Dale

I am not sure that I understand your question.

Seems like you could use excel to create the stress period start times and then paste those into the stress periods dialog. I can't think of a way to do it any faster.

Thanks Alan, that worked. Unfortunately, it leads to more questions. The following is what I want to build for a pumping sequence. Stress periods 1 through 5 are shown. It needs to contineu onward through SP 6000. Is there any clean way to do this?

1 0

2 -962.57

3 0

4 -962.57

5 0

Thanks again,

Dale

I apparently have run into a problem that trumps the rest. The following is from the end of the very small .glo file:

DISCRETIZATION INPUT DATA READ FROM UNIT 19

# MF2K DISCRETIZATION FILE

#

#

# NLAY NROW NCOL NPER TIMEUNITS LENUNITS

1 LAYERS 100 ROWS 100 COLUMNS

6001 STRESS PERIOD(S) IN SIMULATION

THE MAXIMUM NUMBER OF STRESS PERIODS IS: 1000

ABORTING BECAUSE THE MAXIMUM IS EXCEEDED

Any way around this or do I go back to Groundwater Vistas?

So the default maximum number of stress periods for MODFLOW is 1000 right? I posted a version of MODFLOW with the max number of stress periods = 10000 at this ftp site:

Hope this helps.
