External substance "EauSalee" (salt water)
Note :
This external substance is used to model a salt water solution with a boiling point elevation.
The principle of calculation is to consider that the properties of the solution are those of water at a temperature offset by the value of the elevation, itself a quadratic function of the salt concentration.
You will find below the various documents defining the external class:
- Presentation of the model 
- Java code of the external class 
- extUser.zip or extUser2.zip file containing the class
