Parent Command
> OBSERVATION

Subcommand
>>> ELEMENT

Description
This command selects as an observation type the concentration [kg/m3] of a component in a given phase. Concentration is defined as the product of mass fraction of component icomp in phase iphase times density of phase iphase. This observation type refers to an element. Component number icomp or component name comp_name, and phase number iphase or phase name phase_name depend on the EOS module being used. They are listed in the header of the iTOUGH2 output file, and can be specified either on the command line or using the two subcommands >>>> COMPONENT and >>>> PHASE, respectively.

Example
> OBSERVATION
>> CONCENTRATION of BRINE in LIQUID
>>> ELEMENT: A1__1

or

> OBSERVATION
>> CONCENTRATION of COMPONENT No.: 2 in PHASE No.: 2
>>> ELEMENT: A1__1

or

> OBSERVATION
>> CONCENTRATION
>>> ELEMENT: A1__1
>>>> COMPONENT: 2
>>>> LIQUID PHASE
