D. Billaux, J. E. Peterson

Abstract

The purpose of this report is to provide the user with sufficient information to run the program CHANGE: A numerical model for three-dimensional modelling of channelized flow in rock. This report should familiarize the user with program options and modes of operation, input variables, input and output files. In addition, information not strictly needed to run the program, but useful in understanding its internal structure and the flow of computation is provided in the appendices. The appendices cover program variables and arrays, subroutines outlines, a short description of each subroutine, and finally a listing of the code. 7 refs., 4 tabs.
