Two phase flow (Diffusion vs advection) with mesh sizes
Dear all, dear Finsterle, I have a question regarding the mesh size and its impact on diffusion in two-phase flow. I'm curious to know if the mesh size affects the diffusion from element0 to element1.…

Metis and parallel computing in Tough
Hi All, I found many descriptions about Metis in the User's guide of Tough2-MP. However, there is little description of Metis in Tough3. So, is Metis used in Tough3 for parallel computing? Moreover,…

Conductive heat flow in output files?
Hi all, Is it possible to print specifically the conductive heat flow between two blocks? I believe the "HEAT" column in the output file and the COFT files contains all heat components (conductive,…

EOS5 but Helium in stead of Hydrogen
Hello, I am trying to simulate a year long helium injection with varying rates using EOS5. I'm wondering if I would need to change something in the source code for this to run correctly,…

INCON format in the *203t ECO2n samples
In the samples for Tough3 ECO2n, there are several cases whose name ends in 203t where the INCON keyword looks strange to me. For each element, there are 6 lines for the values of the primary…

Heterogeneous field simulation
I was simulating water injection into oil reservoir with a heterogeneous permeability/porosity field using TOUGH3-EOS8. The heterogeneous permeability/porosity fields were realized by modifying the…

Values <1.0E-100 included in SAVE file with improper formatting.
When running with tough3-eos3, we noticed that there were some values for air mass fraction (X2) that were below 1.0E-100, but the "E" was not included.…

Does TMVOCBio in TOUGH3 have any option for 3-phase hysteresis
Hi all, What I recall is that TMVOC did not have Hysteresis options for three-phase capillary pressure and relative permeabilities (see the link). Seems it is still the case in TMVOCbio (in TOUGH3).…

Varying Flow and Enthalpy
Hi, The requirements for the injection are such that an enthalpy value is normally assigned. Given a process of surface system heat transfer, the enthalpy of injection must vary with the production…
