REPORT:
A Numerical Program for Steady-State Flow of Hawaiian Magma-Gas Mixtures Through Vertical Eruptive Conduits


-- Larry G. Mastin, 1995,
A Numerical Program for Steady-State Flow of Hawaiian Magma-Gas Mixtures Through Vertical Eruptive Conduits: U.S. Geological Survey Open-File Report 95-756

System Requirements and Installation

The DOS-formatted disk that accompanies this report contains the following files: The source code file, HICON.FOR, is written in ANSI FORTRAN 77 and can be compiled using any FORTRAN 77 compiler. For simplicity, no graphic output has been supplied; flow properties are written to output files and must be plotted using some other software. This makes the program somewhat less user-friendly, but also makes it possible to compile and use it on any computer platform, with any associated hardware. The executable file, HICON.EXE, will run on any DOS-based computer containing an INTEL ® 80386 or later processor. The executable file may be copied from diskette to a hard disk using the copy command in DOS, or may be used while resident on the floppy disk. The input and output files are supplied as read-only files so that you don.t inadvertently write over them before copying them to another place. You will need to explicitly change their read-only status to modify them. The time (real, not CPU) required for a typical model run using HICON ranges from a few seconds or less (on a 60 MHz or faster Pentium ® -based computer) to a few minutes (on a Data General AViiON ® 300-series UNIX workstation 1 ). Different runs, of course, vary in time depending on the number of iterations required to reach a solution.
