Hi GWB team,
I'm attempting to react a specified volume of fluid with a certain chemistry through a mass of olivine with a certain grain size over a year. I am able to do this using X1t, such that olivine dissolves into the fluid as the fluid migrates through. However, I'd like to essentially add more olivine as the initial olivine is dissolved away. Is there a way to do this? I played around with doing this in React - like the "Flush.rea" tutorial - however that does not let you specify grain size. Another example is this quartz aquifer one: https://academy.gwb.com/dissolution.php which is what I’m sort of aiming to do but I’d like to specify grain size of the aquifer.
As part of this experiment, I'm hoping to keep track of total olivine dissolved, total fluid passing through the system, and chemistry of that fluid. I've attached an initial script and database to give an idea of what I'm trying to do. Thanks for all the help!
