Is it possible to use Perple_X to compute H20 and CO2 EOS? #6

Is it possible? When I usually compute a material i can only choose % of oxides. I ask then If there is an escamotage to do that

Yes, you can evaluate CO2 and H2O EoS directly using FLUIDS, FRENDLY, MEEMUM or VERTEX. The latter three programs require that you specify a thermodynamic data file.

Is there some tutorial how to do that? The purpose is to use them in ASPECT

jadconnolly commented 3 weeks ago

FLUIDS is, I hope, intuitive. FRENDLY requires: that you select a thermodynamic data file (e.g., hp02ver.dat), that you add the line "GFSM T" to perplex_option.dat, and that you select the phase of interest ("H2O" or "CO2"). The calculation with MEEMUM or VERTEX is as that of any other phase diagram section, as with FRENDLY I recommend adding "GFSM T" to the option file. If you have no experience running Perple_X one of the tutorials at www.perplex.ethz.ch may be helpful.

Thank you, i'll check them out!
