## Computer-aided structural engineering (CASE) project: Application of finite-element, grid generation, and scientific visualization techniques to 2-D and 3-d seepage and ground-water modeling. Final report

This report describes new advances in the computational modeling of ground water and seepage using the finite element method (FEM) in conjunction with tools and techniques typically used by the aerospace engineers. The unsolved environmental issues regarding our hazardous and toxic waste problems must be resolved, and significant resources must be placed on this effort. Some military bases are contaminated with hazardous waste that has entered the groundwater domain. A groundwater model that takes into account contaminant flow is therefore critical. First, an extension of the technique of generating an orthogonal structured grid (using the Cauchy-Riemann equations) to automatically generatemore »
