This message was originally posted 8/28/2006] Posted by: Aaron Slowey Hello, React is not converging on the initial composition of my system (08-24-06.rea file attached). The problematic aqueous species seems to be the anion I specify React to charge balance on (either Cl- or nitrate, with no effect on residual, etc.). I'm trying to use the Minteq_gwb4 database, to which I've added 1 new aqueous species (see attached file). I can load this database without any error prior to opening the .rea script. Thanks for any suggestions. Aaron Slowey Posted by: Craig Bethke Hi Aaron, The model doesn't converge because it is not possible for a chemical system containing cinnabar and H2S to be in equilibrium with a reservoir of dioxygen gas. If you set a very low oxygen fugacity (say, 10^-80 or so) the simulation runs to completion. Hope this helps, Craig Link to post Share on other sites
