Because of entering the relation, the parameter Rho has automatically been created. For Rho to be a valid parameter, a dimension should be assigned.

The parameter is automatically created in the Class in focus when saving the relation! |

- Provide a reference for
Rhoand assign it the dimensionkg/m^3.Rhois now a valid parameter. Furthermore, make sureRhois determined by SYS: System/Equation, as a relation is used to determineRho.
What follows now might seem a bit unconventional: a second relation is given for Rho. This is a nice example of how Quaestor works: in a calculation, Quaestor can find numerous calculation paths and automatically chooses the most appropiate one, based on constraints and available data.

An infinite number of relations can be assigned to one particular parameter. |
- Add the following relation (belonging to fresh water) in a similar way as described above:
...
Whenever Rho is needed in the calculation process, Quaestor will note that the watertype is needed to determine the value of Rho, and will ask the user for this value (because it is assigned to be User only).
When you select a parameter in the upper list, the relations of that particular parameter are visible:
