Abstract
VS2DI is a graphical software package for simulating flow and transport in variably saturated porous media in one or two dimensions using cartesian or radial coordinate systems. This software package consists of three components: (i) VS2DTI, for simulating fluid flow and solute transport, (ii) VS2DHI, for simulating fluid flow and energy (heat) transport, and (iii) VS2POST, a standalone postprocessor, for viewing results saved from previous simulation runs. Both VS2DTI and VS2DHI combine a graphical user interface with a numerical model to create an integrated, window-based modeling environment. Users can easily specify or change the model domain, hydraulic and transport properties, initial and boundary conditions, grid spacing, and other model parameters. Simulation results can be displayed as contours of pressure head, moisture content, saturation, concentration or temperature, and velocity or flux for each time step, thus creating a simple animation. The numerical models used for flow and transport calculations are the U.S. Geological Survey’s computer models VS2DT (for solute transport) and VS2DH (for energy transport). Although these models are integrated into the software package, their source codes are maintained as individual Fortran programs that can be compiled and run separately from the graphical user interface. This report provides an overview of the features and capabilities of the VS2DI software package. Detailed instructions on how to use the software are provided by on-line help manuals and tutorials that are included in the software.
