O2 transport

Thanks Jia. I think this is a case where the student merely plugged something into a previous X1T run. I thought it might be the dxplot parameter, but I wasn't sure what it should be set too. Is there ever a reason to have a dxplot of 1e-4? Is there a dxplot value that would be too high? Thanks. Rob

Hi, Two of my students and I ran into an issue where the XTPLOT never rendered after an apparent successful run of X1T. The same parameters were used in a successful REACT run, so it is unclear what happened. Regards, Rob U6+_Acetate_2_Proj5-mod.rea.x1t thermo_GEOL565-2020.tdat U6+_Acetate_2_Proj5.rea.x1t

Hi Jia or Brian, My class has been running X1T to model the transport of O2 created by the reaction of CaO2 (oxygen release compound). I have created a PPT file to illustrate our observations. There are two questions. 1) How does the O2 concentration reach much greater than background concentrations at > double the distance than the flow would allow ? 2) Why does the porosity alter the distance the O2 is transported when the discharge is given in cm/day? Why should porosity matter when these are the discharge units? Regards, Rob X1T-Model output.pptx
