Why MODAEM with GMS?
GMS provides a custom interface to the MODAEM model offering a simple way to set model parameters and a graphical user interface to run the model and visualize the results. Gather background data from a variety of sources from GIS to CAD and access online data from numerous databases of maps, images, and elevation data. GMS allows you to interact with models in true 3D taking advantage of optimized OpenGL graphics and to create photo-realistic renderings and animations for PowerPoint, print, and web presentations.
The MODAEM model is developed by Vic Kelson of Wittman Hydro Planning Associates in Bloomington, Indiana. Unlike finite difference and finite element models, analytic element models do not require a discretization of the problem domain. Rather the model is completely defined by boundary conditions, source/sink terms, and material property zones represented by points, polylines (arcs), and polygons. Since GMS users are already in the habit of building conceptual models in the Map Module using points, arcs, and polygons, analytic element modeling is a natural fit for GMS.
