Setting up initial water chemistry
Hello, I am trying to set up a TOUGHREACT model of reactive transport during upwelling of CO2 and salt, starting by emulating the chemistry presented by Zhang et al., 2016 (attached).…

Pressure loss
Hello, I am using TOUGHREACT to model a core-flood experiment. One end is closed and has CO2 and/or brine injected in and the other is set to be an inactive node to simulate the constant pressure at…

Is it possible to compute a simulation with OH- as primary species?
Dear all, I would like to know if it is possible to compute a simulation by using a database with OH- as primary species. I used the kswitch utility in order to switch a database with H+ to OH- as…

Cells with time-dependent concentration?
Hi, I found that time-dependant boundary conditions in flow are possible in TOUGH2 by using FOFT and GOFT blocks, but is it also possible to have a time-dependent concentration at certain element?…
