Syntax >>>> PARAMETER: index (index_i…) Parent Command all third-level commands in block > PARAMETER and > OBSERVATION Subcommand –   Description (synonym for command >>>> INDEX) Example (see command >>>> INDEX)   See Also >>>> INDEX (p) | >>>> INDEX (o)

Syntax >>>> GAUSS or >>>> NORMAL Parent Command all third-level commands in block > PARAMETER Subcommand –   Description This command generates normally distributed input parameters for Monte Carlo simulations. This is the default distribution. Parameter values will be generated following a normal distribution with the initial guess as the mean, and the standard deviation

Syntax >>>> LOG(F) Parent Command all third-level commands in block > PARAMETER Subcommand – Description The parameter to be estimated is a log-normally distributed factor with which the initial TOUGH2 parameter value is multiplied: p = log10(X/X0) <=> X = X0 * 10pHere, p is the estimated parameter, X is the TOUGH2 parameter, and X0

Syntax >>>> LOGARITHM Parent Command all third-level commands in block > PARAMETER Subcommand – Description The parameter p to be estimated is the logarithm of the TOUGH2 parameter X: p=log10(X) <=> X=10pEstimation of logarithms is recommended if the parameter is expected to vary over a large range of values, suggesting a log-normal distribution of its

Syntax LIST (on any command level) Parent Command any command Subcommand – Description This command provides a list of all commands on the corresponding command level. The list contains the actual upper case spelling of the command as interpreted by the program. Potential keywords are not listed. A complete list of all commands can be

Syntax >>>> INDEX: index (index_i…) or >>>> PARAMETER: index (index_i…) Parent Command most third-level commands in block > PARAMETER Subcommand – Description This command provides a list of integers for further parameter specification. The integers are usually indexes of TOUGH2 arrays, such as IPAR in arrays CP(IPAR,NMAT) or RPD(IPAR), selecting the IPAR-th parameter of the

Syntax >>>> INACTIVE Parent Command all third-level commands in block > PARAMETER   Subcommand –   Description This command makes a parameter inactive. The initial guess provided for the corresponding parameter is transferred to TOUGH2, but the parameter is not evaluated or used for sensitivity analyses, parameter estimation, or uncertainty propagation analysis. Example > PARAMETER

Syntax >>>> GUESS: guess Parent Command all third-level commands in block > PARAMETER   Subcommand –   Description This command provides an initial guess of the parameter to be estimated. If neither this command nor command >> GUESS is used, the initial guess is taken from the TOUGH2 input file. The initial guess is the

Syntax >>>> GAUSS or >>>> NORMAL Parent Command all third-level commands in block > PARAMETER   Subcommand –   Description This command generates normally distributed input parameters for Monte Carlo simulations. This is the default distribution. Parameter values will be generated following a normal distribution with the initial guess as the mean, and the standard

Syntax >>>> FACTOR Parent Command all third-level commands in block > PARAMETER Subcommand – Description The parameter to be estimated is a factor with which the initial parameter guess is multiplied. X=p*X0 <=> p=X/X0Here, p is the estimated parameter, X is the TOUGH2 parameter, and X0 is the initial value of the TOUGH2 parameter. This
