OSTI ID:5696748
CHAINT is a two-dimensional numerical model for the analysis of contaminant transport in a fractured porous medium. The physical processes accounted for include advection, dispersion, diffusion, retardation, radionuclide chain decay coupling, and mass injection. The computational scheme employed by CHAINT is based on a Galerkin finite-element method and block-diagonal frontal solution technique. Continuum portions of the medium may be modeled with two-dimensional isoparametric elements. Discrete features are modeled with one-dimensional elements that are embedded along the sides of the continuum elements. Principal input to this model consists of files from a predecessor MAGNUM-2D simulation of buoyancy driven fluid flow. Output from CHAINT includes a printed report of contaminant concentrations along with postprocessor graphics files. This report contains information relevant to general usage of the CHAINT code.
