PhreePlot

PhreePlot is a program for making geochemical plots and fitting geochemical models to observations with PHREEQC.

Introduction

PhreePlot contains an embedded version of PHREEQC 3. PhreePlot sits on top of PHREEQC and makes it relatively straightforward to do repetitive PHREEQC calculations, the type of calculations that are often needed to make a plot. PhreePlot uses tags placed within the PHREEQC input file to identify places where substitutions are to be made and has several looping mechanisms to control the values substituted. It also contains software for generating Postscript (ps) plot files and optionally a bundled version of Ghostscript for converting these to a variety of other image formats. In addition to normal PHREEQC-type calculations, PhreePlot can be used to generate predominance diagrams, make 2D-contour plots and to fit PHREEQC models to observations using various optimization routines.

Download

• PhreePlot (Version 1) for Win32 and x64 Windows. N.B. It is advisable to use the x64 version if possible. It is likely that the next version of PhreePlot will be the x64 version only.
• If you do not have administator rights to install the above, use this x64 version which can be installed anywhere. You will then have to manually set the PHREEPLOT environment variable to your installation directory and PHREEPLOT_PATH to the directory containing the pp executable.
• Some Linux and Mac OSX binaries are available with installation notes here.
• A brief guide to the installation of PhreePlot.
• Ghostscript 9.52, or locally from gs952w64.exe or gs952w32.exe for converting ps files.
• GSview (Ghostgum Software Pty Ltd) for viewing ps files. Note that this requires Ghostscript 9.52 or earlier.
