How to assign pore pressure gradient
Hi, I have a question in assigning the pore pressure gradient in TOUGHREACT? I tried to assign the pore pressure to each zone by the txt file, but failed. Is there anyone has the experience? Thanks.…

Difference between TOUGHREACT 1.2 and 2
Hi all, I am observing quite different (quantitative) results between 0D and 1D simulations run with the 1.2 version of TOUGHREACT/ECO2N and the 2.0 version.…

Different output results for different max time step (DELTMX) values
~~I am running a Toughreact model. I run this model with the time step of 1200 seconds (DELTEN=1200 s) using different max time step values (DELTMX= Infinite, 15 years,…

Question about constant rate
Hi, everyone, I am trying to add the constant mass injection case in my model. Based on the manual, I uses the "mass" to represent the injector by using the dummy element.…

What does negative H+ concentration mean in TOUGHREACT?
I am running some simuations, the results seem to make sense (including pH). But why does the h+ concentrations are negative? Is there a special calculation to convert h+ to pH?

Restart timestep
When restarting a run after long time calculation (e.g.1000year) and continuing the run until 10000year, I can't start the restart run properly. In the SAVE file,…

Why it takes unbelievable long time to run kinetics?
It seems that TOUGHREACT starts to choke when I add kinetics to the chemistry of the my model. The model runs just fine for equilibrium. But once I add kinetics,…

what if a primary species is not defined in the database?
The modeling I am working on involves some initial species that are not defined as primary species in the database. Although I have figured out how to define a new mineral in the database,…

Database TherAkin10.dat
I need some information about the thermodynamic data from TherAkin10. For example what means k-feldspar k-feldspar-kk or magnesite and magnesite-2 and why is the Log K much greater for magnesite-2
