Easy to use

Visual AEM has a short learning curve, making it an excellent educational tool for introductory fluid mechanics, groundwater modeling, or remediation courses. An automatic model quality checker insures a consistent model nearly every time. Visual AEM requires minimal knowledge about the analytic element method (AEM), and builds upon the users intuition about hydrogeology and groundwater flow and transport modeling.


  • 2D single-layer or vertical groundwater flow modeling (steady-state or with Theis wells)
  • Quasi-3D multi-layer groundwater flow modeling (steady-state)
  • 2D Finite element and Finite difference multispecies contaminant transport modeling
  • 2D Analytical contaminant transport modeling
  • Particle tracking
  • Parameter estimation
  • Transect / cross-sectional analysis

Visual AEM supports the modeling of 2D single and multi-layer steady state groundwater flow using a wide range of high-precision hydrogeologic features, including:

-Rivers / Drains
   Head-, resistance- or extraction-specified
   Head-, resistance- or extraction-specified
Polygonal, circular, or elliptical
-Recharge/leakage Zones
   Circular or polygonal
-Vertical and horizontal wells
-Inhomogeneities in aquifer base
-Inhomogeneities in aquifer thickness
-Inhomogeneities in porosity
-Inhomogeneities in hydraulic conductivity
   Polygonal, circular, or elliptical
-Slurry walls
-Flux-specified and no-flow boundaries
The transport features of Visual AEM are also notable:
-Advection, dispersion, diffusion, sorption, and first-order decay of multiple solutes
-Source Zones
   Initial conditions (aqueous and sorbed)
   Constant concentration
   Constant concentration recharge
-Surface Water Sources & Sinks
   Injection Wells, rivers, and lakes
-Inhomogeneities in porosity
-Inhomogeneities in soil type (for spatially   
 heterogeneous sorption properties)
   Polygonal, circular, or elliptical


Visual AEM contains a multitude of features that simplify the model development process:

-Automatic model quality checking
-Extensive help files and manuals
-Interfaces with Surfer® 7.0 and above
-Up to 30 base maps in .bna or .shp format
-Uses USGS DEMs in *.dem or .grd format for preprocessing rivers and lakes
-Automated mesh generation utilities
-ArcView® and ArcGIS® output options
-Unit conversion utilities
-Stepwise modeling manager
-Extensive editing and zooming tools
-A convenient and powerful object manager
-Tools for editing and creating finite difference grids


Visual AEM is as inexpensive as it gets without us paying you to use it.
