T-X or P-X diagrams

Post by Caio Santos »

Hello

I'm having a problem in trying to calculate a T-x diagram between two rock compositions, at fixed pressure. I actually don't understand what should I list as the "global" composition (first line of the dat file) in this case. Whatever I put as the "global" composition, I always get the same error message: "Input error: X-min and X-max are the same"

Any help would be greatly apppreciated.

Cheers

Hi Caio,

For the first line I usually just use an average of the end-members. Can you attach your THERIN file?

Cheers,
Josh

Hello Joshua

Thanks for your response. I actually tried the average, and got the same error message. In this case I am interested only in the H2O variation, so all three compositions are the same, except for the H content.

For some reason I can't attach the therin file... But since it is very small, I will copy the text below.

Cheers

Caio

Hi Caio,

For domino, enter "BIN 0 1" for either the x or y axis and then T or P for the other axis such as "TC 500 1000".
