There is a small typo in the install.command script. If you open it with any text editor, go to line 19 and change "install2.command" to "install.command". Save, then run it. That should fix the issue.

Windows / Melts for Excel: Server Error ...
Last post by jtmitchell - July 17, 2024, 08:06:05 AM
Hi all,

I'm trying to do some panic modelling for a conference and I've been getting nothing but "server returned no results" errors today, both with updated and non-updated workbook links, and every flavour of Melts. I've been back through the troubleshooting guide and found the log file. It's giving me "invalid xml file received" and "requested URL is not found on the server" even on the default composition it downloads with. I've copied the log below. Has anyone else run into this issue? I'm used to the Excel version being a little wonky at times, but I've left it quite late to try and get this modelling done. Maybe I'm just missing something very obvious!


Thanks in advance!

Website issues, and Miscellaneous / Installing Version 2.3.0
Last post by IsaiahSpring - June 20, 2024, 04:49:21 PM
Hi all,

I am having trouble installing the latest version of MELTS, 2.3.0. After downloading "alphamelts-app-2.3.0-macos-arm64.zip" from the Github and running the install.command I get this error:

Installation aborted or may be incomplete!
Use of uninitialized value $bin in concatenation (.) or string at ./install.command line 482.
Please log out and in and then and run the install script again.
Check the '' directory is in your path then choose 'n' to exit.
Press return to finish.

If anyone has any advice I would appreciate it!

Thanks

Hi Paul,
The software you have developed is excellent and has greatly assisted me in understanding magmatic processes. However, I have encountered some issues during the operation that require your help.

I am a student who has recently been using alphaMELTS to simulate the mobility of the Sc (Scandium) element in layered mafic–ultramafic intrusions. That is, the process of Sc enrichment from a deep magma chamber (5kbar) to near the surface (1 kbar) and ultimately into different minerals (e.g., Cpx, Ilm, Amp).

I have already attempted simulation in the deep magma chamber under isobaric conditions, with an initial composition of Sc at 37.41 ppm. At the end of the simulation, only Cpx showed enrichment of Sc (26 ppm), and other minerals (e.g. Ilm, Amp) did not exhibit enrichment of Sc.

I also tried changing the partition coefficient of Sc in clinopyroxene (D=0.51 to 4), modifying it directly from the default_trace_data.txt file, but it did not work. The exported results show the partition coefficient fluctuating between 0.49xxxx and 0.51xxxx, which is not the value I set.

I would like to ask:
(1) Can the simulation of Sc enrichment in other minerals be performed? (e.g., Ilm, Amp) I saw a post on the forum mentioning that "the system cannot simulate Co and Ni because the partition coefficients of these elements in Ol/Cpx/Opx are unstable............" Is Sc subject to the same issue?
(2) If I want to simulate both major and trace elements, especially the enrichment trends of some key metallic elements, do you have any suggestions?
(3) There are some teaching videos on YouTube from a few years ago, which are basically for macOS and Linux OS. Since my computer operates on Windows, are there any teaching videos suitable for Windows users?


Best wishes,
Jimmy Young

alphaMELTS software has a new home on GitHub!

https://github.com/magmasource/alphaMELTS

v2.3.0 is now available for download. This release brings the suite of alphaMELTS software -- formerly alphaMELTS 2 (v2.2.1) and alphaMELTS for MATLAB/Python (v1.2.2) -- into one open-source repository. The same versioning is now applied to all interfaces, as the majority of edits are to the C library of MELTS functions that is common to all the software interfaces.

The binaries have been repackaged so that users need only download files for the platforms (MacOS, Windows, Linux) and alphaMELTS interface that they intend to use. This arrangement is transitional, while workflows are being developed to package the software for PyPI, Homebrew, CRAN, MATLAB File Exchange etc.

The Caltech-hosted GitList repository and the GitLab-hosted private repository are being preserved as placeholders for previous users of alphaMELTS for MATLAB/Python, but no new members will be added to the alphaMELTS group.

Hi Melina,

I don't think there is an fO2 example in the MELTS-pMELTS directory. There is functionality like that in the newer Equilibrate package but I haven't looked at any of it lately. Your best bet might be to ask on the ENKI Slack channel (enki-portal.slack.com). It's the free version of Slack so you can't see old posts, unfortunately, but queries usually get answered by community members quickly.

Sanidine is an end member in the feldspar solid solution in (Rhyolite-)MELTS. So far as I know, you can't exclude it in Thermoengine without excluding the feldspar phase altogether, although you could might be able to  get around this by removing K2O from your bulk composition.
