Question about ECO2N V2.1 temperature limitation
I am currently running simulations using TOUGHREACT V4.13omp with the ECO2N V2.1 equation of state. During the initialization, the code outputs the following message: “Running ECO2N V2.…

Automated Run-Time Control of TOUGH4 Simulations Using OpenCLAW
Hi everyone, I’d like to share an approach we’ve been using to automatically monitor and steer TOUGH4 simulations during run-time, without modifying TOUGH4 source code.…

TMVOC-Temperature is out of range
Hello everyone. I'm currently learning to use TMVOC, but I've encountered some problems. I've successfully simulated flow under only rainfall conditions, constant head, and isothermal conditions.…

2 versus 3 phase relative permeability
Hi, I hope I can get some clarity on this issue. When you use 2 phase relative permeability to represent a 3-phase situation (for example water, CO2 gas and CO2 liquid in ECO2M),…

TOUGH3-EOS7C failed to converge after 10 years
Hello, I am simulating an injector and producer doublet in a gas reservoir with TOUGH3-EOS7C. It runs well for the first few years and then struggles to converge with very small time steps…

Compiling TOUGH3 source code using quadruple precision
My understanding is that when using double precision, it is generally best practice to avoid models where permeabilities vary by more than ~8 orders of magnitude (defualt `dfac`?).…

TOUGHREACT: single run vs. segmented time runs
Hello everyone, I have a question that has been puzzling me for quite some time regarding TOUGHREACT simulations. If I run a simulation directly for 100 days, and alternatively run it in segments (e.…
