iTOUGH2 version 7.1

Hi, I was trying to run an example with iTOUGH2 (ver 7.1) - T2VOC for sensitivity analysis, but got an error message (screenshot attached). There was no problem when I tried  with same input files using iTOUGH2 (ver 6.5) and T2VOC (EOS10). I wonder if anyone can help me with this error message.

  • Hi Kue,

    Would you mind sending me your TOUGH2 and iTOUGH2 input files (to stefan@finsterle-geoconsulting.com), so I can fix the issue more quickly?


    PS: I very much appreciate it that you added the detailed error message.

  • Hi Kue-Young,

    Thanks for sending me the input files.

    In the iTOUGH2 input file, you selected >> PRESSURE as an observation type, and then had a command line >>>> COMPONENT: 3.

    Note that pressures do not refer to a component, but a phase! You could specify >>>> PHASE : 1 to select the gas phase, but this is the default, so just delete the line >>>> COMPONENT: 3 and it will run.

    I will answer your other questions by e-mail.


  • Hi Stefan,

    Thank you very much for looking into the files. The model runs fine now.

    Many thanks!
