 Add the following relation in Top Goals/Undefined:

Make sure Intpol_Rel_B is dimensionless and determined by SYS: System/Equation.  

...

When Quaestor calculates this function, it determines the value Frame (which is user input). This value is then compared to the values of the given column for X (which is the column Frame of the object Hull), and an interpolated value for Rel_B with respect to the input Frame is assigned to the parameter Intpol_Rel_B. Notice that an @ is used to identify the data within the object.

  Run a solution for Intpol_Rel_B using the process manager and selecting the ship object. Make sure that Intpol_Rel_B is in the class Top Goals/Undefined to see it in the Process Manager. The process manager is crucial here, as static data from the Ships object should be used (which contains the object Hull). For frame, enter 3.20.

Quaestor should return 0.26 for Intpol_Rel_B.

To find out how accurate the interpolation is, we introduce an error. The interpolated parameter uses static data from the object Hull, but we also defined the relative width analytically (the parameter Rel_B).
