| Create Data Input Files
- Make a directory to run ipars
<water>/h1/gxl/IPARS/IPARSv2/work/
mkdir Run
<water>/h1/gxl/IPARS/IPARSv2/work/ cd Run
<water>/h1/gxl/IPARS/IPARSv2/work/Run/ ln -s ../ipars
.s
Note: ipars can be run in the same place as it
was built
- Input file should be compatible with the executable as
far as model/solver/vis etc. are concerned.
- Dimensions should be compatible with the MAX bounds for
arguments as defined in sizefiles.
- When creating an input file it is better to modify an
existing file than start from scratch.
• Do not use TAB symbols or unusual things may happen
!
• Use $ symbol to comment things out in the input
file.
- Copy an existing data input file to the directory where
ipars will be run
• Assume hydrology implicit model is build
<water>/h1/gxl/IPARS/IPARSv2/work/Run
cp
../../data/hydro1.dat mytest.dat
- Modify the input file
• Modify mytest.dat and change TIMEEND to 10.0 (days)
Run IPARS
- Interactive mode
<water>/h1/gxl/IPARS/IPARSv2/work/Run/ ./ipars

Standard Ouput
- Check for errors in output, in particular, for any string
ERR* in the standard output file.
- If everything went well, you should have some results
in the output files according to what was requested in the
input file.
Example: Look at the results in the output file
hydro1.out and in the well
file HYDRO1.WEL
<water>/h1/gxl/IPARS/IPARSv2/work/Run/
ls
hydro1.dat, hydro1.out (Standard output), HYDRO1.WEL (Well
output ) ipars
Restart Run
- Specify restart output time in a data file.
• TIMRES = Time for restart output
• DTIMRES = Time between scheduled restart outputs
• Example: Modify hydro1.dat
TIMRES = 2.0
DTIMRES = 2.0
- Specify restart input/output files when running ipars
• Give restart output file name in an initial run
• Give restart input/output file names in a restart
run
- Initial runs
• Interactive mode
