Constant mass expansion (also called constant composition expansion) examines how a feed behaves volumetric related to the volume at the saturation point.
The user has to give a pressure range and a temperature. The function will then calculate the volume at each point and report them relative to the saturation point volume.

|
TemperatureList
|
Range of double
|
No
|
One column with a number of rows given the list of temperatures to use in the flash calculations
|
PressureList
|
Range of double
|

Output
|
C# : string
|
No
|
Defines the output. (Note currently unused, so just leave blank)
|
Components
|
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.
