Karmina Aquino Posted December 21, 2020 Share Posted December 21, 2020 Hi all, I am interested to unsuppress/suppress Calcite in a React run once a certain ion ratio (e.g. Mg/Ca) is reached. Is this possible? I am just starting to explore adding control scripts to React. There doesn't seem to be much information about this in the GWBreference. Where do you suggest I can begin? Cheers, Karmina Quote Link to comment Share on other sites More sharing options...
Jia Wang Posted December 22, 2020 Share Posted December 22, 2020 Hello Karmina, When suppressing a mineral, it is applied to the whole duration of the simulation. The program will still report the mineral saturation with regards to the suppressed mineral but will not consider it in the system for precipitation or dissolution. Typically, this feature is used to prevent more stable minerals that modelers do not expect of form in the simulation and allow less stable minerals to appear. Suppressed minerals are set before the simulation begins and there's no way to set it to trigger it during the simulation. If you are working with kinetic reactions though, you can set up a customized rate law to set the reaction rate to cease once you reach a certain component ratio of Mg/Ca. If you are interested, please take a look at customized rate laws in section 5 in the GWB Reaction Modeling User Guide. If you would like more help, please provide more details regarding what you're trying to do or an input script that you are troubleshooting. Hope this helps, Jia Wang Quote Link to comment Share on other sites More sharing options...
