I want to simulate the movement of an acidic water through a calcite-bearing soil and graphically illustrate the "banding" that one would see as Fe and Al hydroxides, and thereafter Mn oxides, precipitate. But I am not sure how to setup the advection block to output the correct data to the selected output file. I should be able to do this with one cell, and move progressived pore volumes through. Somehow I need to graphically display the amount of mineral versus a "distance" rather than a pore volume ( i think). One thing I have done is produced a titration curve where I reacted calcite with the water in increments, and indeed it shows Fe and Al precipitating before Mn. But, it would be nice to have a "depth versus mineral concentration" plot that shows the banding I have observed in the field. Can you provide any suggestions? Thank you.
