SUTRA Version 2.1
-
A model for 2D or 3D saturated-unsaturated, variable-density ground-water flow with solute or energy transport
Information
-
SUTRA is a model for saturated-unsaturated, variable-density ground-water
flow with solute or energy transport. SUTRA
Version 2.1 allows the use of irregular meshes in both
2D and 3D simulations and offers convenient incorporation of input data from separate files,
greater user control over time stepping, and interpolation of observations in time and space to
facilitate inverse modeling.
A Release Notes file containing installation instructions is included with the software. It can also
be downloaded separately using the link below.

simulation. It includes news, advice on how to get started using SutraSuite,
an overview of the software, a gallery of SUTRA simulation results,
answers to frequently asked questions, a glossary, in-depth discussions of
selected topics, and technical support information, including a
troubleshooting guide.
Software (Version 2.1, June 2008)

To download the installation files, click on the links below. (Some web
browsers will automatically run the installation program after downloading it.
If your browser does not automatically run the installation program, save the
installation file on your computer and run it by double-clicking on its icon.)
To install the software, follow the instructions provided by the installation
program. It is recommended that you accept the default
settings during installation.
NOTE: The installation files may be updated from time to time to fix bugs or
make other improvements. A "critical" update is one that is required
for the proper functioning of some aspect of a code or example problem. If
a critical update to an installation file has been issued since you
last downloaded that file, it is highly recommended that you
check the list of updates on the "SutraSuite
Installation File Updates" page to determine whether the update
affects your SutraSuite applications. If so, uninstall your
current installation (if one exists), then download and install the latest revision of
the installation file using the corresponding link below. Minor updates are of lesser
importance and may be considered entirely optional. For details on how to install an
update, or to view a complete listing of updates to the installation files for
SUTRA and the SUTRA examples, see the "SutraSuite
Installation File Updates" page.
