Hi Daniel, I have attempted to replicate the electrolyte simulation from the wiki page using the latest version of DWSIM 4 (version 10). Water calculations are working well: pure water has a pH of 7 and as I change the Hydron molarity, the pH changes accordingly. Unfortunately, once I add 2 M NaCl with the same initial compositions as in the wiki, the solver fails to converge. Everything looks the same as in the wiki, but the new equilibrium stream composition is not updated, nor is the pH calculated right. Let me know if I'm missing something. Thanks, Hector |
