  • Fractionation calculations, zero_mode problem

    dear all, i just saw a problem in a fractionation calculation that made me realize that the value of "zero_mode" in perplex_option.dat should always be set to

    p.s., the difference between the 6.8.0 and 6.7.5 version of JF's pelite calculation is due exactly to problem hugo mentioned in msg 1414 (the stability of H2

    dear all, JF and debaditya's comparisons made me realize that 6.8.0 is functioning correctly, but that a poor parameter choice was causing it to resolve phase

Group Description

This is a discussion group for users of the Perple_X suite of programs for calculating and displaying phase diagrams, phase equilibria, and thermodynamic data. Users of any and all of the other programs designed for this task are also welcome. Students (including undergraduates) are particularly encouraged to join and participate in discussions on the uses and applications of phase diagrams, phase equilibria, and thermodynamic data. This list is intended both to be a place for inexperienced users to ask “how do I…” questions, and for general discussion as to the finer nuances of the use of such programs for those with all levels of experience. Discussions of topics of a petrological nature necessary for the understanding of the diagrams generated are encouraged, as are discussions of which diagrams and calculations are best suited to answering specific geological questions.

This is a moderated list in hopes of keeping it SPAM free. Therefore please include a brief sentence or two showing that you are a human, and have an interest in geology/ phase diagrams, phase equilibria, and/or thermodynamic data. If you are willing to serve as a moderator of the list (more moderators mean sorter delays between individuals joining the list and getting approval), please let us know.

New members are encouraged to browse the archives to see if we've already discussed questions of interest. Note: There is a database (button to the left) recording the citations of journal articles (or book etc.) mentioned on the list, and in which message it was mentioned. Anyone may add to this database; please do so if you are the person who cites a paper or book here for the first time.
