Syntax
>> MASS FRACTION (comp_name/COMPONENT: icomp) (phase_name/PHASE: iphase) (CHANGE/DELTA)
Parent Command
> OBSERVATION
Subcommand
>>> ELEMENT
Description
This command selects as an observation type the mass fraction of component icomp in phase iphase. This observation type refers to one or more elements. 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 iTOUGH2 header, and can be specified either on the command line or using the two subcommands >>>> COMPONENT and >>>> MASS, respectively.
Example
> OBSERVATION
>> MASS FRACTION of BRINE in LIQUID
>>> ELEMENT: A1__1
or
> OBSERVATION
>> MASS FRACTION of COMPONENT No.: 2 in PHASE No.: 2
>>> ELEMENT: A1__1
or
> OBSERVATION
>> MASS FRACTION
>>> ELEMENT: A1__1
>>>> COMPONENT: 2
>>>> PHASE : 2
