Question about Restart in TOUGHREACT
Hello Everybody, I am struggling to get running a restart and I would really much appreciate your insights. I'm using eos1 in toughreact_V2. The first run is a 2d model in which I have 8 minerals,…

Failed mass balance for CO2 if "Two Fluid Phases conditions" employed
Hello everyone, I am trying to run the geochemical equilibration of brine with a sandstone rock composed of several minerals (mostly quartz 70%, around 4% carbonates and some feldspars and clay…

How to set-up a model that reacts only on the surface
I am trying to set-up a model that simulates a leaching experiment. The material is very impermeable (flow is not supposed to go through) and based on existed data,…

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,…

Rapidly reducing temperature in cells and MINC problem
Hello, I'm trying to recreate the simulation of the Coso EGS as published by Kovac et al on the Stanford Geothermal workshop in 2006. I have two questions that I would be grateful to have some…

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 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,…

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,…

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
