Dear Paula,
Great, thanks for the clarification.

I also got some replies from the conference organizer as well. Sorry for missing the Goldsmith workshop since I was ill at that time period.

Hopefully and definitely, I will be able to attend the next MELTS conference in Newzeland. Please keep me in the loop if there is anything new that comes through. Thank you very much.

Best regards,
Ri Cao

Hi Ri,

I'm not sure. They haven't updated the website fully. I guess you can add the workshop when registering for the conference, but I haven't tried yet. To be honest, I'm still tying up loose ends from the recent workshop at Goldschmidt!

The full price is supposed to be 160 NZD. Students and early-career researchers (as defined here) should get a reduced rate of 60 NZD. I will follow up next week to see how you get that rate.

Best wishes,
Paula

Hi Antoine,

Ah, sorry that didn't work. You could try easyMelts. It can do everything that the old GUI can. I don't know if it will get around the comma problem but it would be interesting to see:

Dear Paula,
Sorry for my interruption again and hope you are doing well.

I just realized that there is another MELTS workshop for the IAVCEI conference in New Zealand, early next year. I was wondering how shall I sign up for this workshop? Are there any links for registration and how much will that cost? Thank you very much and I look forward to your response.

Sincerely,
Ri Cao

Hello Paula,

Thank you for your answer!
Yes I have read Jose's post before. Lucky him, the trick didn't work from me!
I have tried to install MELTS on linux and it does the same thing...
Thanks anyway,

Best regards,
Antoine.

Do you have ALPHAMELTS_QUICK_OUTPUT set? If not, then see if setting it helps.

If you already have that variable set, then the best I can suggest is to break the calculation up into smaller chunks and then concatenate the output.

News and updates / Melts Calculations Slowing down

« Last post by aprajitmahajan on July 26, 2022, 05:19:47 am »

Hello,
I'm trying to run melts on a table_file with around 1300 entries. It's generating the right auto_batch file and corresponding melts files.

When it comes to running melts on the compositions, it initially melts a composition every 7-8s which is what I expected since that's how long it takes when an individual melts file is run. However, after a while the processing speed drops drastically and the program takes close to 3-4min to run a single composition. Is there a fix to do it faster? What is the possible reason for it becoming so slow?

I'm saving all the outputs in the same file using the save_all command in the settings file.

Thank you for the help,
Aprajit

You probably need to change the keyboard input from French to English:

News and updates / Comma Problem

« Last post by Antoine.fr on July 25, 2022, 04:26:49 am »

Hello,

I installed rhyolite_MELTS for Mac OSX on my laptop that is setup for European countries.

When I start the program the GUI pops up and everything seems to work as I have access to all the different functions. However, I stared to have a problem when I entered my chemical compositions. Indeed, when I enter "AL2O3= 17.38",  the soft returned the value "17,000". I have the same problem when I load the MORB test file. I tried to enter "17,38", but the program does not accepts the comma decimal separator. I need to use the "dot" decimal separator and he returns the comma and drop all the decimal numbers. I have tried to change the decimal separator from "," to "." in operating system and keyboard, but this does not help.

Do you have any idea how to solve this issue?
Thanks for your help,

Antoine Bézos
