Correct application of fractionate solids/fluids?

[oliviahogg]

Hello!
I'm running some fractional crystallisation simulations where I am interested in the cumulative mass of the fluid, solid and liquid at each step. I just wanted to check that selecting fractionate solids and fractionate fluids was the correct way to do this?
Thus far I have been using the Phase_mass_tbl output and calculating the cumulative masses of fluid/liquid(given anyway)/solids from there.
For FC of a basalt w 1 wt% H2O at 200 MPa through to a final mass of ~10g liquid (69 wt% SiO2), I am getting a total cumulative mass of fluid1 (i.e. adding up the mass in each step) =0.35g. To me this is quite low but it may be right hence why i wanted to double check with you first!

also the alphamelts manual refers to frac_water - is this used interchangeably with frac_fluids?

Thanks again,
Olivia

Is this alphaMELTS 1.9 or 2?
