  Provide a reference for rho and assign it the dimension kg/m^3. Rho is now a valid parameter. Furthermore, make sure rho is determined by SYS: System/Equation, as a relation is used to determine rho.

The following 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.

  Provide references, dimensions and determined by values for Cb and DISP. Cb has no dimension (-), DISP should be in tons (t). Just press ok if Quaestor notes that tons is no base dimension (kg), it is just to inform you. We covered this by dividing DISP by 1000. The determined by values should be VR: User Only for Cb, and SYS: System/Equation for DISP, as the block coefficient is input and the displacement is determined by a relation.

8    Creating a solution

Let's perform our first Quaestor calculation. A solution is always determined by one or more Top Goals. A top goal is a parameter (or object) that is your final calculation target, in this tutorial it's the displacement of the ship.
