Environmental Modeling Software

BioF&T 3-D models flow and transport in the saturated and unsaturated zones in two or three dimensions in heterogeneous, anisotropic porous media/fractured media. BioF&T allows real world modeling not available in similar packages. Model convection, dispersion, diffusion, adsorption, desorption, and microbial processes based on oxygen limited, anaerobic, first order, or Monod type biodegradation kinetics, as well as anaerobic or first order sequential degradation involving multiple daughter species.

Features

Transient 1-D or 2-D Cartesian (x,z) or 2-D Radial (r,z) water flow and multi-species dissolved phase transport solution in the unsaturated zone uncoupled with 2-D or 3-D flow and multicomponent aqueous phase transport in ground-water aquifers. This feature enables complicated conditions.

Temporal and spatial variations in the source (i.e., residual dense or light nonaqueous phase liquids and/or other nonpoint contaminations) and, given the initial conditions, changes in loading to ground water are computed and updated internally.

Spatial variation in recharge/injection.

Model multiple pumping and/or injection wells, or trenches.

Simulation of heterogeneous and/or anisotropic porous media with (or without) fractures based on a dual porosity approach.

Rectangular 2-D/3-D prism or isoparametric quadrilateral/hexahedral elements to accurately model irregular domain and material boundaries, hydraulic, and physical boundaries.

Computationally efficient matrix solution by conjugate gradient method with preconditioning.

BioF&T allows highly accurate representation of irregular site boundaries, uneven ground surface and complex subsurface geology with the three-dimensional mesh editor.
