SET
Function:
allows
the user to specify which temperature and pressure/volume is to be used
for the calculations, and whether the ternary plot produced is
calibrated in mass fraction or mole fraction. An initial starting
composition in terms of mass fraction or mole fraction may also be set
in which case the graphics cursor will not appear until the
calculations are complete. Note that for replotting a magnified diagram
the centre of the area of interest must be specified as a composition
through use of the SET command.
Parameters:

temperature


pressure 

n(*)


w(*) 
Defaults:

pressure =
101325 Pa


temperature =
undefined


n =
1 
Examples:

set
temperature=1010 pressure=1e5 !


set
n(1) 0.4 n(2) 0.5 n(3) 0.1 !


set w=1
!

Parameter
values:
TEMPERATURE takes
the value <temperature>/UNDEFINED

The units of temperature are KELVIN.

PRESSURE takes
the values <pressure>/UNDEFINED

The units of pressure are Pa.

N

takes the value
<any number>/UNDEFINED

N

takes the values
<any number>/UNDEFINED

W 
takes the values
<any number>/UNDEFINED 
N(*) 
takes the values
<any number>/UNDEFINED 
W(*) 
takes the values
<any number>/UNDEFINED

General comments:
The
default calibration on the ternary plot axes is mole fraction. This can
be altered to mass fraction by assigning a value to W. Return to the
default is accomplished by assigning a value to N. Component amounts
greater than unity are normalised to 1 mole (or, if weight fraction is
to be used, 1 kg). Note that the ternary results file will store tie
line data in a form according to whichever calibration is used. If
REPLOT is to be used subsequently to obtain a magnified portion of a
diagram the area of interest must be specified by entering a
composition using the set command.
