Intpol_Rel_B=LININT(@Hull,2,@Frame,@Rel_B,Frame)

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

...

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

...

• Add the following

...

• relation to your Top Goals/Undefined class:

Error = Intpol_Rel_B - Rel_B

in which Error Error is a dimensionless SYS parameter. Run a solution for this parameter, Intpol_Rel_B will be calculated by Quaestor automatically because it is required by Error. Make sure you use the process manager Process Manager to select the Ships Ships object as dataset. For frame Frame, enter 3.20 again.

The solution in two-digit format (-0.00) will be presented in the list of the Workbase. When you select this solution, more digits are shown in the Frame Viewer (figure 2a) or Explanation window (figure 2b). Note that you can change the number of decimal places presented in the Workbase by changing the value Decimal places in the Slots & Properties window.
