alphaMELTS 1.9

This package contains the binaries, scripts, documentation and example files for alphaMELTS, the public text-based front-end to the MELTS, pMELTS, and pHMELTS models. A list of files in this package is included below; full explanations are in the documentation. This is version 1.9; a brief change log is at the end of this file.

  • Fixed recording of Amoeba model primary melt composition
  • Option to save Amoeba starting guess after adjustment (e.g. for fO2)

1.3 (August 12th 2013)

  • Assimilant composition may be input as separate (liquid and) mineral phase files
  • Added simple way to evaluate latent heat of crystallization
  • Fixed bug when restarting alphamelts to calculate integrated melt
  • Set PTpath line no. so run can be continued at exactly same place after failure
  • Fixed various problems with automatic updates, particularly on 64-bit Windows
  • Various fixes to Perl scripts and corrected typo in example settings file

1.3.1 (April 17th 2014)

  • Fixed memory leaks that could cause segmentation faults in certain cirumstances

1.3.2 (May 23rd 2014)

  • Fixed segmentation fault during file read if trace elements are off
  • Imported corrected melilite file from Mark Ghiorso
  • Option to return to menu if forget to turn off phase diagram mode

1.4 (July 14th 2014)

  • Fixed bug that Paul found in flux melting routines
  • Tweaks to subsolidus fO2-buffering make it less likely to hang
  • Suppressed debugging output for nepheline and other phases
  • Addition of 64-bit Windows version and Windows 8 support
  • Minor updates to scripts, e.g. making path message clearer on Windows
  • Added title to Morb.melts (see http://dx.doi.org/10.1146/annurev.earth.25.1.221)

1.4.1 (November 8th 2014)

  • Fixed bug in cubicquad routine for aggregation of melt
  • Upgraded check for updates routines on Linux and Mac
  • 64-bit Linux binary is more backwards compatible

1.5 (August 8th 2015)

  • Added a PTgrid mode and make all ALPHAMELTS_MODE variables case insensitive
  • Added isograd 1 & 2 menu options (…METASTABLE_ISOGRAD deprecated)
  • Changed behaviour of isograd 1 ('stable isograd') to have phase 'just in'
  • Added find wet liquidus to isograd 2 (solids are still 'metastable isograd')
  • Only assimilate MgO-bearing phases in reverse fractionation
  • Updated opx to match Mark Ghiorso's version
  • Fixed bug in choice of biotite models
  • Fixed bug when minerals are assimilated as separate files with no fO2 buffer
  • Updates to install.command to allow user to specify default settings file etc.

1.6 (June 23rd 2016)

  • Allow constraints (e.g. isentropic) to be turned off temporarily with menu option

  • Fixed serious bug in …ALTERNATIVE_FO2
  • Fixed assimilation of non-stoichiometric mineral phases
