Form transformation based on transverse section areacurve with transforming function

With the development of CAD in ship design, the traditional method of transformation from the parent form, namely 1Cp, can't meet the requirement of CFD in flexibility. It is an effective solution to expanding the old method using a transforming function based on the section area curve of the parent form. And the software is also designed. The theory is advanced, the method is practical and the software is feasible by giving some examples of real ship form design.
