Syntax >>>> HEADER: nskip or >>>> SKIP: nskip Parent Command all third-level commands in block > OBSERVATION   Subcommand –   Description This command identifies the number of lines to be skipped before reading data. Data reading starts nskip+1 lines after the command line >>>> DATA, or on the (nskip+1)-th line of the data file […]

Syntax >>>> FORMAT: format Parent Command all third-level commands in block > OBSERVATION   Subcommand – Description This command accepts a FORTRAN format statement for reading data. By default, data are read in free format following the >>>> DATA command or directly from a data file. If a column contains non-numeric characters, formatted input can

Syntax >>>> FACTOR: factor Parent Command all third-level commands in block > OBSERVATION Subcommand – Description This command provides a conversion factor with which the data are multiplied so they comply with standard TOUGH2 units. The conversion factor is also applied to the standard deviation (see command >>>> DEVIATION (o)), i.e., the measurement error must

Syntax >>>> DEVIATION: sigma (ADD NOISE) Parent Command all third-level commands in block > OBSERVATION   Subcommand –   Description This command specifies the standard deviation sigma of the observations. The squares of the standard deviations constitute the diagonal elements of the a priori covariance matrix C . zz The specified value sigma is assigned

Syntax >>>> DETREND: timewindow (time_unit) / -npoints Parent Command any third-level command in block > OBSERVATION Subcommand none Description This command detrends observed and calculated system responses by subtracting a moving average of the values either within a given time window (given as a positive realtimewindow) or within a given number of points (given as

Syntax >>>> DATA (NO DATA/ZERO DATA/FILE: file_name) (time_unit) Parent Command all third-level commands in block > OBSERVATION Subcommand – Description This command reads a list of observation times and the corresponding data. Each list will be referred to as a data set in the iTOUGH2 output file. An annotation is generated for each data set,

Syntax >>>> CUMULATIVE (TIME) Parent Command all third-level commands in block > OBSERVATION   Subcommand –   Description Returns the cumulative value, i.e., the integral of the model output within the time window. If keyword ANALYZE or RAW is present, the measured data will also be integrated (i.e., they are assumed to be breakthrough curves).

Syntax >>>> CONSTRAINT: lower upper Parent Command all third-level commands in block > OBSERVATION Subcommand –   Description This command allows imposing a constraint on a model output by penalizing the objective function if the calculated system responses z is outside the specified bounds, i.e.: z < lower or z > upper. The penalty function

Syntax >>>> COMPONENT comp_name/: icomp Parent Command >>> ELEMENT >>> SOURCE (o)   Subcommand –   Description This command identifies a component either by its name (comp_name) or the component number (icomp). A list of allowable component names for the given EOS module can be obtained from the header of the iTOUGH2 output file. Example

Syntax >>>> COMBINE: isetdwa Parent Command all third-level commands in block > OBSERVATION   Subcommand –   Description Combines the current data set with a previously defined dataset idetdwa for the purpose of calculating set-specific data-worth metrics. Example > OBSERVATION >> GAS SATURATION >>> ELEMENT : A1113 >>>> ANNOTATION : Sg 1/4 >>>> POTENTIAL >>>>
