NOTE: As of July 2011, Perple_X
6.6.6+ is the
default version of the Perple_X. An
unfortunate consequence of the change in versions is that most of the examples
and tutorials referred to here are out of date. The out-of-date examples and
tutorials are, in most cases, useful because the basic information passed
between the various programs has not changed although many of the prompts have
been eliminated or reordered.
The Perple_X on-line documentation
illustrates certain specific types of calculations. These illustrations often
assume some basic knowledge of the Perple_X
programs; for beginning users it may be more helpful to work through
the off-line tutorial and/or examples.
Flow charts of program structure
is not current, so prompts and computational results obtained
now with Perple_X may differ from those in
the documentation, despite this problem, working through the offline
documentation may still be the best of learning how
to use Perple_X. Note that the chapter
dealing with fixed bulk compositions has been supplanted by
An on-line guide to example problems done with Perple_X.
The original technical documentation is a potpourri of different kinds of information on topics
such as the equations of state implemented in Perple_X
for compounds and solutions and the structure of various Perple_X
data files. The technical documentation is not up-to-date and it is probably not a useful document for Perple_X novices.
README Files (ASCII)
These files contain various types of technical information (file formats,
etc) for specific Perple_X programs.
Scripting and other OS specific utilities/instructions:
Links to various (user supplied) scripts and/or facilities that automate
aspects of Perple_X. Scripting
written for earlier
versions of Perple_X may not function as
written in current versions (6.6.6+) of Perple_X.
autoVertex - an OSX/Unix perl script that automates running VERTEX with
the "auto_refine" option. This script is now obsolete if VERTEX is
run with the "auto_refine" keyword set to "auto", however the script provides
a template for scripts to perform other tasks.
These are notes prepared (with emphasis on elementary), for short
courses some years ago. The first part deals with some basic thermodynamic principles,
especially G-X diagrams. The second part offers a brief (out of date) comparison
of computational methods, and elaborates on aspects of Perple_X algorithms.
