Melt vol% isopleth

Post by Mohammad_Miri »

Dear all


I want to calculate isolines for vol% of melt component of a system using Domino.

I have used Volume [ccm], Molar volume [g/mol], Volume% (of solids), and Amount [mol] options for SOLUTION PHASES and BULK ROCK in Domino but unfortunately in most cases, all the isolines lie on a single reaction curve (the first melt producing reaction) like the attached Fig.

Would you help me to do it correctly?

Best wishes

I suggest you calculate the stability conditions of each phase at a specific point in interest stability field
by running "domino
choose the database
choose the X axis (T)
choose the Y axis (P)
then choose "POINT" for the "calculation definition".
choose the precise point (x temperature, y pressure)
you get the volumes and densities of the stable phase.
you can see this in "OUT" file
then you can calculate the isolpet according to the results.
I hope it is going to work
