DIFFUSION Block
Hi, I am using TOUGH+Hydrate and I'm fairly new to it and learning as I go. I am using injection of water into a gas bearing reservoir. I wanted to include the diffusion block and tried the example…

Enthalpy Discrepancy
Hello There, I was just wondering what the reference state for the enthalpy of water in TOUGH2 is? The reason is I would like to define water infiltration (precipitation) with a temperature of 20˚C.…

Non convergence when considering non-isothermal or molecular diffusion in TOUGH2 ECO2N
I am using TOUGHREACT V3.32 to model CO2 injection in a radial 2D mesh with different layers in the z-direction. Before running the reaction part of the problem I wanted to test the flow part was…

Convergence becomes difficult after CO2 breakthrough (ECO2N)
Hi, I want to know why the convergence becomes difficult (so the time step becomes very small, or simulation terminates) near or after phase breakthrough.…

Instant release EOS7R
Hello everybody, To simulate an instant release of a radionuclide in eos7r, we have to insert a no-zero value of the component in the INCON block. This value should be the mass fraction of the…
