Hi,
I am trying to modeling the reaction of a hyperalkaline Ca-rich rich fluid with atmospheric CO2 (log PCO2 = -3.5). I have tried several approaches using both cations or anions as balance species and swapping Ca++ out for a mineral (Portlandite), but each time, the simulations crater because of failure to converge. How do I get around this problem?
