Re: water, vapor and heat coupled modeling in 2D/3D
Very short answer: Yes, all TOUGH codes can do what you intend to do.

Re: SAVE file
Thanks, Florian, for this information. This is the TOUGHREACT format (4E15.9; iTOUGH2 and TOUGH3 use 5E10.4). Is there a T2B documentation? If so, it should indicate for which TOUGH package this…

Re: SAVE file
@Florian DELSANTE Florian, Please check the TOUGHREACT manual or contact Eric Sonnenthal. I'm actually curious to learn where you got the idea that permeabilities can be specified in INCON. Stefan

Re: SAVE file
Florian, Glad you are charging ahead. Just to complete the topic and answer Eric's question: TOUGH3 inherited some (but not all) of the iTOUGH2 features documented in the report "Enhancements to the…

Re: SAVE file
Hi Eric, I have to clarify this to avoid (further) confusion: iTOUGH2 does have element-by-element permeabilities or permeability modifiers (for all three directions) and other user-specified…

Re: Flux question
Peter, Try to use COFT (no need for a code modification). If you need to customize, check subroutine FGTAB under COFT in file eco2n.f for all relevant indices.…

Re: System of equations for EOS4
Only briefly, If you want to specify a heat flux, the elements should not be "inactive" (if inactive, they would "swallow up" all the injected heat); just specify GENER heat source terms to all…

Re: Non-Darcy flow of oil above bubble point
Hi Lee, Not sure whether you are talking about the reservoir model or wellbore model. Standard TOUGH2 cannot simulate non-Darcy flow, but both iTOUGH2 and TOUGH+ have the Forchheimer equation with…

Re: iTough2 parallelization by PVM
Keshvad, I assume with "VPM" you mean "PVM" and with "OPM" you mean "OMP". PVM has been used as a very secure message passage tool across heterogeneous clusters (which is more challenging than a…

Re: iTough2 parallelization by PVM
Keshvad, Andri is right; I just repeat for clarification: (1) iTOUGH2 embarrassingly parallelizes multiple forward runs that are independent of each other (e.g.…

Re: Non-convergence when considering permeability heterogeneity
Jim, Two things: (1) It seems you tried to run this file with ECO2M instead of ECO2N (but that's not the issue). (2) If you have a dummy domain SEED in your input file with DROK=POR=0.…

Re: Non convergence when considering non-isothermal or molecular diffusion in TOUGH2 ECO2N
Hector, Upfront: I don't think I can help you, because: (1) I could not run the file as sent: I needed to (a) remove illegal tab stops in block DIFFU; (b) remove all values after porosity in the…

Re: System of equations for EOS4

Re: System of equations for EOS4
Dear Ali, As you correctly state, a total pressure of 6 bar is below the saturated vapor pressure at 240 C. This means that your reservoir has to be initialized as single-phase gas.…

Re: Convergence becomes difficult after CO2 breakthrough (ECO2N)
I don't think a general answer can be given without digging into the details. Can you check whether the simulation tries to cross the saturation line (which is not possible in ECO2N)?…

Re: Setting permeability anisotropy with Voronoi elements
