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,…

Re: EOS7 - Specifying initial conditions
@Alfredo Battistelli Thanks, yes it is the proper choice. I decided to use EWASG instead.

Re: TOUGH3 + PEST?
I think there is a sample using TOUGHREACT in the iTOUGH2-PEST manual, but they are mostly reading the reactive model outputs not the flow model. As for you question: Parameters: permeabilities,…

Re: TOUGH3 + PEST?
Definitely, I agree. I'm just checking if I can avoid creating the template and instruction files from scratch, as I'm sure iTOUGH2 already has to have them hard-coded somewhere.…

Re: TOUGH3 + PEST?
Are there TOUGH2 "instruction and template files" within the mio.f90 or it2pest.f that I can reuse as a starting point to create a TOUGH3-ewasg instruction file?

Re: EOS7 - Specifying initial conditions
And by the way, I have decided to use EOS7 instead of EWASG because I don't want to simulate changes in porosity and permeability due to salt deposition.
