Hello David, some days ago we were in contact about the database llnl.dat. Now, we have some problems modelling analyses of waters, which were in contact with steel slags regarding species distribution. I attached 3 of these analyses which have nearly the same composition (CH1A, CH3A, CH4A). However, two of these analyses (CH3A and CH4A) do not get convergence. We have just checked ion balance and it's ok. So what's wrong with these analyses, since CH1A can be modelled without problems ? With regards, Bernd
