In this paper, the author tries to improve the accuracy of the start solutions for the aerodynamical global optimization of the FC shapes by replacing the three‐dimensional, analytical hyperbolical potential solutions with new own developed hybrid numerical solutions for the Navier‐Stokes layer (NSL). These solutions have also analytical properties and are split. It follows a more rapid convergence and, consequently, a speed up of the computation time. The evolutionary iterative optimum‐optimorum theory uses these hybrid solutions after the first step of iteration and easy allows the weak interactions with the structure, via new and/or modified initial constraints, requested for the structure point of view.
