There may be others, depending on the exact calculation performed or the source and / or partition coefficients used (e.g. D = D(P,T,X)). See Smith & Asimow (2005) and documentation for fuller details.

Documentation and examples that should help in getting started with alphaMELTS are given on the far right. The MELTS camp presentations and exercises are an amalgation of more than one short course, and are rather old; newer materials from specific sessions are linked on the alphaMELTS archive page. You can search the forum for queries and examples (you only need to log in to post). Certain threads have been flagged as frequently asked questions or tutorial-style posts and we are gradually adding more. Bugs in the software or mistakes in the documentation that are not serious or have a reasonably simple workaround are listed below. They will be fixed in alphaMELTS 2, as appropriate.

Errata and bug fix details specific to alphaMELTS1.9 (last updated July 4th, 2020).

The most convenient online documentation is the HTML version but this can no longer be maintained. The most up to date version is now the online PDF version. To download, please right-click the link and choose 'Save As...' or similar, rather than saving from your browser's PDF viewer. This will preserve the document outline and bookmarks for navigation. If you wish to browse the documentation without downloading, we recommend using Firefox (click the 'Toggle Sidebar' and 'Show Document Outline' buttons towards the top left corner of the window).
For reasons beyond our control, automatic notification when there is a new version of alphaMELTS is not working on any operating system. Instead, we will let you know via the forum, Facebook, twitter etc. For alphaMELTS 2 the run-alphamelts.command script will check for updates, rather than the alphamelts2 executable, which should make automatic notification easier to test and maintain. Sorry for any inconvenience.
Several new features, and multiple bug fixes, have been implemented in alphaMELTS 2 since VM alphaMELTS 1.9 (Lubuntu 16.04 LTS) was released in August 2018. Some features were introduced at the NSF-sponsored alphaMELTS workshops; others are somewhat documented in the alphaMELTS 2 GitLab repository. As of July 2nd, 2020 the new VM alphaMELTS 1.9 files (Lubuntu 18.04) include the updated alphaMELTS 2, alphaMELTS for MATLAB/Python, and much more. We recommend updating to the current VM alphaMELTS 1.9 if you are using a previously downloaded version, or one that was distributed at an alphaMELTS workshop. Note that this will be the last VM alphaMELTS release, although users of the 64-bit version will be able to apply future updates to alphaMELTS 2 and alphaMELTS for MATLAB/Python manually.

Paula Antoshechkina – contact her for any type of query but particularly those related to alphaMELTS settings, input and output, installing / using Perl, and Windows operation; also questions about other MELTS software, including the rhyolite-MELTS GUI (especially on the WSL) and the Magma Chamber Simulator (see the LINKS tab for details).

Paul Asimow – contact him with algorithm questions, especially those related to the pHMELTS model, subsolidus calculations, trace elements or other features not available in the GUI versions of MELTS.

Mark Ghiorso – contact him for details about the underlying MELTS and pMELTS models, as well as the newer rhyolite-MELTS plus mixed H₂O-CO₂ fluid variants, and other tools available on the ENKI and OFM websites (see the ABOUT US and LINKS tabs and the MAGMA links page for brief descriptions).

If you are having problems running alphaMELTS then please try to describe the calculation being attempted in some detail (e.g. include file and keyboard input and the messages or output you got, if any).
