seaman Posted July 31, 2018 Share Posted July 31, 2018 Comparing React result from GWB 11 to results from GWB 6 and GWB 8. My solubility values are always a bit higher than the earlier estimates in the same concentrated background solutions. I get same results for solubility in Act2 in pure water. Is there a difference in how the activity corrections are done in the earlier versions? That is the only thing that I can see to explain the differences. Any help is appreciated Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted July 31, 2018 Share Posted July 31, 2018 Hi, Do you have an example input file that demonstrates this behavior? Thanks, Brian Farrell Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...
seaman Posted August 1, 2018 Author Share Posted August 1, 2018 Attached are the output files. The only difference is NaNO3 as ug/L the actual concentration or as ng/L. Makes about a 33% difference in TcO4 solubility. John ngperL NaNO3.txt ugperL NaNO3.txt Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted August 1, 2018 Share Posted August 1, 2018 Hi John, I don’t quite understand. It sounded like a single React input file was producing different results in GWB8 vs. GWB11. But now you’re saying you’ve changed the Na+ and NO3- concentrations in the input as well? If you want me to see whether the software is behaving differently from one release to the next, I’ll need a consistent input file (.rea) that I can run myself. I need to see what database (and activity model) is used, how the model is set up, the units that are used, the species that are loaded, etc. Thanks, Brian Quote Link to comment Share on other sites More sharing options...
