The total number of shape-defining parameters for a typical parametric model of a flow-exposed geometry (like a ship hull, turbomachinery or engine component) in the CAE platform CAESES®, can typically reach the range of 20 to 50. This means that for complex free-form geometries the number of degrees of freedom is still so large that, when using a direct optimization approach taking into account all parameters, a high number of function evaluations (CFD-calculations) would be required to identify trends with respect to the necessary geometry modifications leading to an improvement of the considered objective function(s). Because of the long computation times, this approach becomes infeasible, especially when dealing with complex flow situations.
