HST3D:

A Computer Code for Simulation of Heat and Solute Transport in 
Three-Dimensional Ground-Water Flow Systems

The Heat- and Solute-Transport Program (HST3D) simulates ground-water 
flow and associated heat and solute transport in three dimensions. Over 
the years since the release of Versions 1.0 through 1.4, various 
additions, modifications, and corrections have been made to the 
original simulator. Major changes included in Version 2 are (1) a 
revised data-input file with all spatial information described by 
coordinate location; (2) a new iterative solver for the matrix 
equations based on a generalized conjugate-gradient method; (3) an 
evapotranspiration boundary condition; (4) a division of the simulator 
output into many files; (5) a new set of output files designed for use 
by post-processing programs for graphical visualization and for flow 
totalization; (6) a pre-processor for evaluating dimensioning 
requirements; and (7) a post-processor for totalizing boundary flow 
rates and cumulative amounts. The post-processing program for graphical 
visualization must be supplied by the user. Version 2 of the simulator 
has been verified using five test problems selected from the published 
literature. One involves heat transport, four involve solute transport, 
and all have variable-density fluids.
