Ross McCartney Posted February 3, 2016 Posted February 3, 2016 Hi, I am trying to model a dynamic system in which I want to allow a mineral to precipitate once the saturation ratio exceeds one but when the saturation ratio later declines below one, I do not want it to re-dissolve. Can anyone suggest approaches as to how I might do this in GWB (I have version 10 Professional). Many thanks, Ross. Quote
Brian Farrell Posted February 3, 2016 Posted February 3, 2016 Hi Ross, I think you’ll want to use kinetics for this problem. To get the desired functionality, you’ll need to write a simple custom rate law. There is an example very similar to the problem you’re describing in section 5.2, Rate law scripts, of the GWB Reaction Modeling Guide. Hope this helps, Brian Farrell Aqueous Solutions LLC Quote
