This function lets the user trace a line when fixing a given property. The property's that can be fixed are:
•Pressure •Temperature •Enthalpy •Entropy
The function can trace only trace inside a multi phase area.
The function works by starting performing a flash at the given temperature and pressure.
The routine will then trace the fixed property in the given direction.

|
FixedProperty
|
C# : string
|
No
|
Property that is fixed on the line. Value input are:
•Pressure •Temperature •Enthalpy •Entropy |
Direction
|
C# : string
|
No
|
Direction in either pressure or temperature.
|
StopProperty
|
C# : string
|
No
|
Where to stop the curve. Valid input are:
•Automatic - The curve stops when it cannot continue •Pressure - User gives the stop pressure. •Temperature - User gives the stop temperature •Enthalpy - User gives the stop enthalpy •Entropy - User gives the stop entropy |
StopValue
|
C# : double
|
No
|
Value depends on the argument: StopProperty
|
Output
|
C# : string
|
No

|
Distribution
|
C# : object
(Expect a range of double)
|
Yes
|
Gives a range with the distribution of the polymer. Can for example be used if 2 flash calculations are liked as 2 separation tanks.
