iTOUGH2 Command Index
This is the iTOUGH2 command index in logical order. Click on any command for a description of the command syntax, the name of the parent command, the name of subcommands, as well as the purpose and effect of the command along with an illustrative example.

There are three main blocks in the iTOUGH2 input file, identified by one of the following first-level commands:

The first block (first-level command > PARAMETER) is used to identify the TOUGH2 input parameters that will be subjected to parameter estimation, sensitivity analysis, or uncertainty propagation analysis. The second block (first-level command > OBSERVATION) is used to identify the TOUGH2 output variables that will be compared to observed data for model calibration. The third block (first-level command > COMPUTATION) is used for various program options and computational parameters.
