iTOUGH2 Features for TOUGH Users

  1. TOUGH input files can be directly used in iTOUGH2 without modifications – great, right?
  2. The iTOUGH2 executable includes all EOS modules, and memory is allocated dynamically – you only need to compile the code once (i.e., no need to recompile when a different EOS module is used, or your model is growing). In addition, no need to worry whether you licensed the wrong EOS modules.
  3. Tired of preparing GENER tables with time-varying generation rates? With iTOUGH2, you can input time, rate and enthalpy in one row in free format; doesn’t this make your soring eyes smile?
  4. In addition, you will have many more options to put in time-varying boundary conditions EASILY: e.g., time-dependent Dirichlet boundary conditions, free drainage boundary conditions, material-specific volumetric rates, sinusoidal rate changes, reinjection of produced fluids, or something specific only to you, specified by yourself.
  5. If you do not like separating one simulation into a few periods because you have time-varying boundary conditions, iTOUGH2 can make it happen by using the RESTART option. Link pre- and postprocessors to your TOUGH simulations using the PEST protocol.
  6. Have a big problem? No problem! With iTOUGH2, you can have element names up to 9 characters in length and you can choose from several element-naming conventions when using MESHMaker.
  7. The world is heterogeneous! Choose to specify element-by-element permeabilities or permeability modifiers in the ELEM block, or map permeabilities from an external file, or assign property regions, or internally generate and estimate spatially correlated property fields using geostatistics in combination with pilot points.
  8. Are you lost in the land of Voronoi? Conveniently assign properties and generation rates to regions – and estimate their shapes at the same time!
  9. Can’t get enough MOP options? Use more MOPs (MOMOP) and multiply the ways you can make TOUGH run better or worse.
  10. Get physical! Additional functions and processes include one-dimensional hydrogeomechanics, semi-analytical radial heat exchange, active fracture model, additional capillary/relative permeability functions, non-Darcy flow, and fully coupled overland – subsurface flow allowing you to come out of the ground.
  11. The good things that go in come out even better: you will have many more options to print out your results for visualization, including time series of specified variables and convenient extraction of any TOUGH output variable for contour plot.
  12. Make executive decisions during a TOUGH execution (i.e., request an output on the run, put simulations to sleep and wake them up again, or kill a run decisively but gracefully).
