Frederick Gyaase Posted May 7 Share Posted May 7 I am trying to get this reaction together but there a lot of parameters that I don't have. 1. I want to know if these parameters can be found in a particular data base on Geochemist's Workbench or 2. They are in built. The parameters i need are in the screenshot attached below. I am using Fond Du Lac rock. In the third picture, I have indicated a section in a red ink, what is the best value to put there? how do i get the values in the last picture?

Jia Wang Posted May 7 Share Posted May 7 Hello, You can review the GWB Reactive Transport Modeling User Guide for how to set up a simulation in X1t and X2t. You would need to provide information (e.g. kinetic rate constants) to create a simulation on your own. Though, if the software is new to you, I would recommend that you start with the single-node applications (SpecE8 or React) and familiarize yourself with how to configure chemical systems before jumping into a reactive transport model. There are a plethora of resources to help you get started. I would recommend starting with the GWB Essentials User Guide, in section 2 Configuring the Programs. Information on setting up various types of reactants can be found in the GWB Reaction Modeling Guide. I would recommend starting in section 2 Getting Started with React when you are ready. You can find the guides under the "Help" menu of any GWB applications or by going to the Docs pane on your GWB dashboard. All examples in the guides can be found in the Scripts folder, where the GWB is installed. There are also a variety of fully worked examples available on the GWB Academy. Hope this helps, Jia Wang Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...

Frederick Gyaase Posted May 8 Author Share Posted May 8 I tried inputting my values and after running, this is the outcome I got. I don't know what could be wrong. Kindly help me. Thank you. Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted May 13 Share Posted May 13 Hi Frederick, It looks like there is probably some problem with the initial system you defined. If you attach your .x2t file we can try to see what the issue might be. Regards, Brian Farrell Aqueous Solutions Quote Link to comment Share on other sites More sharing options...
Frederick Gyaase Posted May 13 Author Share Posted May 13 Hi Brian, Please find attached the .x2t file. Thank you. x2t_resume.x2t Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted May 13 Share Posted May 13 Hi Frederick, Your nodal blocks are quite small, which would be fine except that you've constrained the Na+ and Cl- components in terms of in absolute units (mass in g) instead of relative units (e.g. concentration in g/kg solution). So, that is equivalent to setting up extremely high Na+ and Cl- concentrations. You've set up the rest of the fluid in terms of relative units (concentrations of HCO3-, Ca++, and Mg++ are all in mmol/kg), so I think you'll want to use "/kg" units for the Na+ and Cl- as well. Cheers, Brian Quote Link to comment Share on other sites More sharing options...
