FREE DEMONSTRATION SOFTWARE AND PUBLIC DOMAIN PROGRAMS
Listed below are DEMOS of some of the software IGWMC offer, as well as some free, public domain software (indicated as PROGRAM). Detailed description of most programs can be found on this web site under the IGWMC Software listing. All the programs are set up as self-extracting files, which can be activated by typing the name of the file at the DOS prompt, or at the 'RUN' command from the Windows file menu, followed by the parameter -d (to include archived subdirectories). Follow the instructions in the README.TXT, READ.ME, or README.1ST files first (after extracting them!)
Because some of these demos consist of a rather large number of files, you are advised to create a separate directory first, and copy the demo to this directory, before extracting the files.
If you have software or software demos you want to post on this site, send us an email, and we will give you the necessary instructions.
3DADE - A Fortran computer program for evaluating a series of analytical solutions of the 3-Dimensional Advection-Dispersion Equation.

Argus ONE - The Argus Open Numerical Environments (Argus ONE) enable you to easily and intuitively prepare your data for any modeling package, finite element as well as finite difference based. By automatically linking the physical data you enter in GIS layers to grid blocks or mesh nodes and elements, Argus ONE keeps your data reusable. Changing your mesh or grid doesn't require you to re-enter your data. Argus ONE integrates a variety of tessellation modules including the Argus MeshMaker®Finite difference grids module and the Argus MeshMaker Triangular and Quadrilateral finite element modules.
AT123D - AT123D is based on an analytical solution for transient one-, two-, or three-dimensional transport of a dissolved chemical or radionuclide or heat in a homogeneous aquifer with uniform, stationary regional flow. The program assumes a stationary flow field parallel to the X-axis and allows for retardation (based on reversible instantaneous linear equilibrium sorption isotherm) and first-order decay.
AT123D-AT - This updated version of AT123D corrects for errors in the original AT123D for pulse sources, and also includes new numerical integration schemes that allow one to accurately simulate rapidly changing transient sources. New series solution approximations for finite-depth aquifers and checks for steady state nodes are included to improve solution accuracy and efficiency. The new program is rewritten using FORTRAN 90 standards, and still runs all legacy input files for the original AT123D. In addition, AT123D-AT has additional input options for new numerical integration methods, and includes new output options for creating areal plume plots and time series plots at selected monitoring points.
