Abstract: Methods and systems for optimizing the design of aerodynamic surfaces are provided. They include in the design process of an aerodynamic surface of a body which moves through a flow field, the following: preparation of a CFD simulation of said body; resolution of the CFD calculation for specific conditions of the flow field and for obtaining flow lines of the flow on said surface; calculation of at least one geometrical variable of the surface, such as, for example, the normal curvature, according to the direction of said flow lines; and simultaneous visualization of the surface of said body and of at least one geometric variable. Additionally, at least one variable of the aerodynamic flow, such as, for example, a pressure gradient, may be calculated and visualized.

Abstract: Method and system to optimise the surface design of an object by optimising one or more of its objective functions J, which includes the following stages: a) Provide an initial geometry (51) of the surface, including its NURBS definition, and define as optimisation parameters p of the same a subset of the NURBS control points; b) Generate a computational mesh (53) of this defined surface by a set of points Pi; c) Determine for each point Pi of the computational mesh (53) the corresponding point in the NURBS geometry (51); d) Evaluate the objective functions J of the surface by a numeric simulation; e) Optimise the objective functions J by modifying the values of the optimisation parameters p; f) Generate a modified computational mesh (53?) corresponding to the modified NURBS geometry (51?) derived from those new values of the parameters p, and return to the stage d).
