I just tried to invite you both on Slack, though I am not sure it will work (seemed to want an @caltech.edu email address). If not, try emailing Mark Ghiorso (ghiorso AT ofm-research.org) and he can add you.

MacOS / Re: OpenGL vs. Metal?

Last post by Paula - Today at 11:33:10 AM

The Validation Failed happens on all (or at least most) versions. It doesn't seemed to affect how easyMelts works.

If  'Liquidus&RedistFeOx' is missing, then make sure you have clicked save after inputting the P and T, and clicked save again after inputting the composition.

Dear Melina,

I have the same question regarding the LLD for a volcanic system that I'm studying. I've also been using the "MELTS v1.0.2 fractionation" Jupyter notebook on the ENKI portal server for this and I wanted to know if you figured out how to change/set the oxygen fugacity? (can't access the Slack channel as my email address is not recognized).

Thank you very much in advance for your answer,

Best regards.

MacOS / OpenGL vs. Metal?

Last post by MDNorman - December 07, 2024, 02:42:48 PM

I seem to be having a problem with the requirement for having an OpenGL 3.3 compliant GPU on my Mac when running easyMELTS. In the terminal window I get an error message
"Starting GLFW context, OpenGL 3.3
Linking program.
Validation Failed: No vertex array object bound."
The computer is a desktop circa 2021 running Sonoma (14.6). It has an M1 chip. It seems to be running Metal rather than OpenGL.
easyMELTS does launch but there seem to be some functions missing such as 'Liquidus&RedistFeOx'.
Apologies if I am missing something. Any advice appreciated.

Hi all,

I am curious if there is any way to back track what the activities of the component oxides are?

The tutorial folder isn't supposed to be in the downloaded package. It was left over (only in the Apple Silicon version) from how alphaMELTS was packaged before the move to GitHub, sorry. The files you need are all in the folder that the README is in: https://github.com/magmasource/alphaMELTS/tree/main/examples/app

You can download individual files by following their links and clicking 'Raw', e.g:
https://github.com/magmasource/alphaMELTS/blob/main/examples/app/Morb.melts

Hi,

I downloaded and installed the standalone app version of alphaMelts for macOS (Apple silicon) (alphamelts-app-2.3.1-macos-arm64). However, the tutorial folder is still empty and I can't locate the Morbs.melt file that is supposed to be there to do the tutorials (following the steps mentioned in the READme page on GitHub (https://github.com/magmasource/alphaMELTS/blob/main/examples/app/README.md).

Can someone please suggest how I get the file?

I'm sorry I had posted a batch file.

hyd.melts and hyd1.melts are exactly the same with just the filenames being different. I have two different batch files referring to each of them, used separately.
