Overview of CFEST Groundwater Code
One of most advanced groundwater technologies


CFEST (Coupled Fluid, Energy, Solute Transport) is a three-dimensional finite-element code for analyzing isothermal and non-isothermal groundwater flow, energy, and solute transport in groundwater systems. CFEST code can be used to:
  • Simulate both confined and unconfined aquifer systems.
  • Conduct coupled and decoupled groundwater flow and solute transport analysis
    in a constant-fluid-density environment.
  • Perform density-dependent flow and transport evaluations.

Key Features

  • Interfaced integrated grid generation capabilities.
  • Model external model boundary, rivers, lakes, faults, and other features are
    modeled in “natural shapes” without distortion.
  • Three-dimensional elements are generated internally which reduces manual
    labor and ensures the continuity of all interfaces of three-dimensional brick
    elements with adjoining elements.
  • Interfaced GIS (Geographical Information System) and 3D plotting/animation
    tools assist in easy-input file generation and results evaluation.

Illustrative samples of CFEST Models:
Long Island Groundwater Reservoir Model (1976) (a) 3d model; (b) Variable layers, & (3) Input Displays Long Island was simulated on small computer with 170 K memory as well as on CRAY computer
EPA (Superfund) San Gabriel Basin – 170 Sq. Mile area – CFEST was 3D model of whole basin. CFEST results were used for OU boundaries and ROD negotiations
Sea Water Barrier Project conceptual model, post processing results- display of injected mass distribution, travel time, and interactively generated fence diagram
