SLAEM (Single Layer Analytic Element Model) is the single-layer version of the program. MLAEM/2 (Multi Layer Analytic Element M odel) can access two layers while the number of layers supported by MLAEM is limited only by hardware. The AEM family of computer programs, presently SLAEM, MLAEM/2, and MLAEM, are based on the Analytic Element Method developed by Dr. O.D.L. Strack. For a description of the Analytic Element Method, see "Groundwater Mechanics" by O.D.L. Strack (Prentice-Hall, 1989). The computer programs are intended for modeling regional groundwater flow in systems of confined, unconfined, and leaky aquifers. All programs run under Microsoft Windows 95, 98 and NT. The programs are native windows applications and are accessed via a modern and flexible Graphical User Interface (GUI) as well as via a command-line interface. The latter capability makes it easy to drive the program from other programs such as Arc-View, ARC/INFO, and PEST. The programs create files from data entered graphically via the GUI. These files can be read in later. The programs read DXF-files and produce BNA files that may be read by other programs such as SURFER.

The program can be purchased from Scientific Software Group and Hydrology Software.
