MELTS software users forum

At the forum you can get help with any MELTS software, request features and report bugs. There are tutorials, examples and additional documentation.
AlphaMELTS software

alphaMELTS is a text-based front end to MELTS / rhyolite-MELTS, pMELTS and pHMELTS. Download and info for Versions 1.9 and 2 (Mac, Linux or Windows).
Geodynamics

Integration of melt formation and migration into mantle flow models. Includes a coupled scheme that uses the alphaMELTS interface (GyPSM) and proposed future work.
$Thumbnail: S-X plot: fractional melting of a pyroxenite-peridotite mixture in the Fo-En system$
Movies

Movies of phase diagrams for adiabatic decompression melting of peridotite and pyroxenite. Includes mixed sources that are in thermal but not chemical equilibrium.
Applet

Online tool for visualization of binary phase diagrams. Includes a tutorial, examples and downloadable Windows software for the ternary version (opens in a separate window).
Source

Code, scripts, examples on a GitList server. alphaMELTS and workshop-related files; also precompiled tools and add-ons for a variety of MELTS calculations (opens in a separate window).
GSA Workshop

Join us in sunny Anaheim, CA, Sept 20/21, 2024, for a 1½ day Life Along an Active Margin-themed short course (#506) featuring the newest alphaMELTS software (opens in a separate window).
MCS Workshop

Join Paula & the Magma Chamber Simulator team online, Oct 1/2, 2024, for a post-Goldschmidt workshop on computational petrology research projects (opens in a separate window).
🔥 New MELTS software! 🔥🔥

Interested in easyMelts, alphaMELTS 2, or αMELTS for MATLAB/Python? The alphaMELTS VERSION 2 and LINKS tabs have details on how to get access them.
MELTS Facebook page

Keep up to date with all software in the MELTS family on the dedicated Facebook page. The About page lists alternative ways to get MELTS user support.
LEPR+ database

Development server for LEPR3 / TraceDs, and DCO/EPC databases. The LEPR+ production server is at lepr.earthchem.org and accepts data through the EarthChem Library (ECL).
xMELTS

Information about the next generation of MELTS model, which is currently under development. Includes a Supplementary Calculator for new spinel and garnet volume models.
