And now I have both in agreement. I'm not sure what is happening but if you can re-create my original problem and provide insight that would be great. A student in my class pointed it out to me this morning so I was working on it with her before trying it on my own as well. I have been using the reactant times option (both above and below 1) to scale the amount of minerals added.

Hi Brian, I am running 10.0.8. I am getting inconsistent results trying to figure this out! I am wondering if the output isn't clearing when I run a new model or something. I re-built both models and am now getting the same behavior for both where the output doesn't match the plot. Alexis

I ran a simple reaction path model reacting quartz, k-feldspar, and muscovite with dilute solution. When I add the minerals in the reactant tab as volumes (cm3) the saturation indices in the output file in early steps do not match what it plotted. However, when I convert the volumes to mass (g) by hand and add the minerals in the reactant tab as mass the saturation indices in the output file match the plot. The plot is the same for both volume and mass added cases but the output files are not. I am attaching the two react files. In both cases K-feldspar reaches saturation at x=0.1 according to the plot, in the case where mineral are added by mass the output matches the plot, but in the case where the minerals are added as volume the output file shows k-feldspar, quartz, and muscovite saturated in the first step. addition_mass.rea addition_volume.rea

This is more of a bug report than a question I think. I am teaching a class using GWB 9 and we keep running into an issue of the plot and output files not updating even though input or reaction parameters have changed. I have had this problem, and now three of my students have also had this problem. I'm guessing there is no way to fix this but if there is please let me know. In case anyone else has the problem: saving a script file, closing and restarting the program fixes it and the plot and output files will update again.
