It is very important to optimize the shape of the flow passage in order to minimize the pressure drop through it. The typical examples are observed in the designing of air duct inside the automobile, the external flow passage around the car, the flow passage inside the pump, etc. We have developed a new method to predict the optimized shape of the flow passage. It is implemented into the specialized CFD code called Shape-Designer. The code is very unique in the sense that it does not require the candidate of the optimized shape to the user. It automatically predicts the shape by itself.
