Unexpected temperature increase at the bottom grid

Hello everyone, I am simulating the evaporation process in the vadose zone (1-D) using EOS3 (via PetraSim). When I activate molecular diffusion, I notice an unexpected temperature increase at the…

INCON not creating correctly from INPUT (very new user)

Hello! I am in the early stages of learning how to run TOUGH2. I have been provided an INPUT file (titled "sam7c3"). When I try to run the program, I get an error in the OUTPUT that states "CANNOT…

Time dependent DELV (PI/BH)

Dear community, I am trying to use a DELV source type to match some well data. However, every well start at producing at a different time. Then, it is needed to make them available at different times.…

T2WELL/ECO2M phase transition issues

Dear TOUGH community, I am trying to model CO2 injection into a saline aquifer. I have a model using T2WELL/ECO2M for coupled modeling, but there is a problem with convergence......…

Changing the number of COFT and FOFT

Dear TOUGH community users, I use TOUGH2 and specified over 100 elements and connections for FOFT and COFT. Those FOFT and COFT are exactly written in the input file.…

Compiling T2Well-ECO2N Using Visual Studio 2022

Hello everyone, I currently have the source code for T2Well-ECO2N, and I had previously succeeded in compiling it using Visual Studio 2017. However, since I can no longer install VS 2017,…

Modify capillary pressure unit by unit

Hi, everyone I have recently read a lot of coupling programs carried out based on the TOUGH series of software, and I noticed that they have an equation for modifying the capillary pressure,…

Query on Early Steady State in Methane Discharge Model at 1% Hydraulic Gradient

Dear TOUGH2 Group, I am modeling methane discharge from a 1m^3, source producing methane at a rate of 1.16E−7 kg/(s⋅m^2). The objective is to observe accumulation and migration through a homogeneous…

Integrated CO2 injection modeling for studying flow distribution aspects in well (&well formation?) in CO2 injection wells in Tough2-ECO2M

Dear All, I am doing my Master's Thesis about CO2 modeling with phase changes (critical, liquid and gaseous form). Could you tell me please, is it possible to make such modeling in Tough2? - if so,…

Increasing Injection Rate

I am currently working on a model where the reservoir permeability is only a few mD, but the injection rate is set at 3 kg/s. In the existing model, when the injection rate reaches 0.…

Simulation result files always maintain their original size

Hello everyone, I am using TOUGHREACT to simulate the chemical reaction of CO2 injection into deep saline reservoirs and caprocks. The input files I defined are as above,…

The results of Example 2 in the ECO2M manual

Hello. I have a question about Example 2 of ECO2M. In Example 2 the residual water saturation is set to 0.3. However, in the results, the water saturation is 0 near the injection well.…
