Definition

Field	Contents	SI Unit Example
`inject_ID`	Injector identifier. (Integer, maximum 10 digits)
`unit_ID`	Unit Identifier. (Integer, maximum 10 digits)
`inject_title`	Injector title. (Character, maximum 100 characters)
`N`_gases	Number of gases. (Integer, 1 ≤ `N`_gases ≥ 100)
`I`_flow	Mass versus time function input type flag. = 0 Mass is input. = 1 Mass flow is input - the input scale factor on time is also applied to mass flow. (Integer)
`fct_ID`_M	Mass of injected gas versus time function identifier. (Integer)
`fct_ID`_T	Temperature of injected gas versus time function identifier. (Integer)
`Fscale`_M	Mass function scale factor. Default = 1.0 (Real)	$[kg]$ or $[\frac{kg}{s}]$
`Fscale`_T	Temperature function scale factor. Default = 1.0 (Real)	$[K]$
`Ascale`_T	Abscissa scale factor for time based functions. 1 Default = 1.0 (Real)	$[s]$
`mat_ID`ⁱ	Material identifier that identifies the gas (`i=1,2...N`). (Integer)
`Molar_Fraction`ⁱ	Molar fraction of injected gas (`i=1,2...N`). (Real)
$f c t_I D_{m f}^{i}$	Molar fraction of injected gas versus time function identifier (`i=1,2...N`). (Integer)

Comments

The sum of Molar_Fraction must be 1.0 at any given time.
The $f c t_I D_{m f}^{i}$ are function identifiers used to define variable molar fraction with time. The function must be defined with the same time abscissa. If $f c t_I D_{m f}^{i}$ > 0, Molar_Fraction is not used.
